Trip Essentials Checklist
Your trip essentials should be organized by which bag they go in, not by what category of thing they are, because that's the decision that actually goes wrong. The rule that sorts everything: anything you can't replace, or can't survive 24 hours without, goes in your personal item, since that's the only bag guaranteed to stay with you. Medication, documents, chargers, phone, and one change of clothes live under the seat in front of you. Everything else is negotiable.
Skip the blank-page problem. Our free packing list generator builds a list for your destination, trip length, and season in about a minute.
Updated August 2026. Airline bag sizes, TSA rules, and battery regulations change. Confirm carry-on rules with your airline and current screening rules at tsa.gov before you fly.
The Trip Essentials Rule: One Bag Is Guaranteed, Two Are Not
Here's why bag-first beats category-first.
Your checked bag can be delayed, misrouted, or lost. It happens to a small percentage of bags, but "small percentage" is not "never," and it always happens on the trip where it matters.
Your carry-on can be gate-checked. On a full flight, when the overhead bins fill, the airline takes roller bags at the gate and puts them in the hold. You get almost no warning, and you don't get the bag back until baggage claim.
Your personal item, the bag that fits under the seat in front of you, is the only one that physically stays with you the entire trip. Nobody takes it at the gate.
So the sorting question for every item is simple: if this bag disappeared for 24 hours, would I be fine? If the answer is no, it moves up a level.
| Bag | Can it be separated from you? | What belongs there |
|---|---|---|
| Personal item (under seat) | No | Irreplaceable, medical, documents, power, one outfit |
| Carry-on (overhead bin) | Yes, gate-checked on full flights | Clothes, toiletries, shoes, anything you'd miss but survive without |
| Checked bag | Yes, delayed or lost | Bulk, liquids over 3.4 oz, anything replaceable at the destination |
Most packing advice never says this out loud, and it's the whole game. Two people can pack the same objects and have completely different trips depending on which bag those objects were in when the bin filled up.
Personal Item: The Bag That Never Leaves You
Keep this deliberately short. A stuffed personal item defeats the purpose, because you can't find anything in it and it doesn't fit under the seat.
Documents and money
- Photo ID or passport (see our travel document checklist for what your specific trip needs)
- One credit card and one debit card from different banks
- Some cash in local currency
- Boarding passes, downloaded rather than relying on airport wifi
- Printed backup of your key confirmations if you're going somewhere with unreliable data
Medical
- All prescription medication, in original labeled containers, in quantities for the whole trip plus a few days
- Any device you need (inhaler, EpiPen, insulin, CPAP supplies, glucose monitor)
- Backup glasses or contacts, plus your prescription written down
- A small pain reliever and antihistamine supply
Power
- Phone
- Charging cable plus wall block
- Power bank (this must be in your carry-on, and the current rules are below)
- Headphones
Comfort and the 24-hour outfit
- One change of underwear, socks, and a shirt, rolled tight
- Toothbrush and a travel toothpaste
- Reusable empty water bottle, filled after security
- Snack that isn't a liquid, since a bar clears security and hummus does not
- Layer or scarf, because planes run cold and it doubles as a pillow
That's it. If you're using a backpack, that list leaves room. If it doesn't leave room, something in it belongs in the carry-on.
The 24-hour outfit earns its space more than anything else on this list. One clean shirt and clean underwear turns a lost-bag day from ruined into annoying.
Carry-On Essentials: The Bag That Might Get Gate-Checked
Everything here should survive being taken from you at the gate with 30 seconds of warning. That means no medication, no chargers you need in flight, no documents.
- Clothing for the trip (see the tables below by trip length)
- Toiletries in a quart bag, ready to hand over at the checkpoint
- Second pair of shoes, packed sole to sole in a bag
- Any bulky layer you're not wearing
- Reading, notebook, work things you'd like but don't need
- Laundry bag or packing cube for dirty clothes
- Small day bag that folds flat, for the destination
Two habits pay off here. First, pack the quart bag where you can pull it in three seconds, since not every security lane lets liquids stay in the bag. Second, make sure the bag actually fits before you're at the gate arguing about it. Our carry-on size checker compares your bag against the airline's published dimensions, which vary more than people expect, and the sizer at the gate is the version that counts.
Checked Bag: Bulk and Liquids
Only pack a checked bag when the trip genuinely needs one. When it does, the rule is the mirror image of the personal item: only put things in here you could buy again at the destination without much pain.
- Full-size toiletries and anything over 3.4 oz
- Shoes beyond the two pairs you're carrying
- Bulk clothing, coats, sports gear
- Gifts and souvenirs (wrapped gifts can be opened for screening, so don't wrap until you land, and see flying with wrapped gifts)
- Tools, nail scissors, razors with removable blades, anything sharp
- Aerosols over the carry-on limit
Never put in a checked bag: medication, chargers for essential devices, jewelry, cash, laptops, cameras, house keys, or anything with a lithium battery that isn't installed in a device. Spare lithium batteries and power banks are prohibited in checked luggage entirely.
Photograph your packed checked bag before you close it. If it goes missing, the claim goes faster with a picture of the contents and a picture of the bag exterior.
Toiletries Bag for Travel: Build It Around the 3-1-1 Rule
Your toiletries bag has one hard constraint if you're carrying on: every liquid, gel, cream, paste, and aerosol has to be in a container of 3.4 oz (100 ml) or less, and all of them together have to fit in one quart-sized clear resealable bag, one per passenger. The container's printed size counts, not how full it is. Our full breakdown, including the medication and baby exemptions, is in the TSA liquid rules guide.
The base kit:
| Item | Liquid? | Best travel form |
|---|---|---|
| Toothbrush | No | Any, plus a cover |
| Toothpaste | Yes | 3 oz travel tube, or toothpaste tabs |
| Shampoo | Yes | 3 oz bottle, or a shampoo bar |
| Conditioner | Yes | 3 oz bottle, or a conditioner bar |
| Body wash | Yes | Skip it, or a bar of soap |
| Deodorant | Depends | Solid stick is not a liquid. Gel and spray are |
| Sunscreen | Yes | 3 oz tube, or a solid sunscreen stick |
| Moisturizer | Yes | 1.7 oz jar fits fine |
| Razor | No | Safety razors need blades in checked; cartridge razors are fine in carry-on |
| Medication | Exempt | Original containers, declared separately |
| Contact solution | Yes | 2 oz travel size, or declare as medically necessary |
| Hairbrush, hair ties, clippers | No | Any |
| Nail clippers | No | Allowed in carry-on |
| Nail file | No | Metal files are allowed |
The solids trick is the single best space upgrade in packing. Solids are not liquids, so they don't touch your quart bag at all:
- Shampoo and conditioner bars replace two of your nine slots and last far longer than a 3 oz bottle
- Solid sunscreen sticks replace the bulkiest item in most bags
- Toothpaste tabs are a small tin instead of a tube
- Stick deodorant is already the solid version, so just don't buy the gel
- Solid perfume and lotion bars exist and travel well
- Bar soap replaces body wash entirely
Swap four items to solids and a family of two can share one quart bag with room left, which is the difference between a carry-on trip and a checked-bag trip.
One honest note: bars need to dry before they go back in the bag, or they turn everything soft and slimy. A small tin or a mesh bag solves it. That's the actual tradeoff nobody mentions.
Electronics and the Power Bank Rules
Electronics are where a packing list turns into a compliance question, and the rules changed recently enough that a lot of published advice is out of date.
The current power bank rules, effective 27 March 2026 under new ICAO guidance:
- Maximum two spare batteries or power banks per passenger
- Carry-on only. Spare lithium batteries and power banks are prohibited in checked bags, full stop
- They must stay accessible at your seat, not in the overhead bin. That's the newest part, and it's the one people get caught by. Keep them in your personal item or a seat pocket
- No charging in flight and no charging from the power bank in flight
- Under 100 Wh: allowed with no airline approval needed
- 100 Wh to 160 Wh: requires airline approval in advance
- Over 160 Wh: banned from passenger aircraft entirely
Most consumer power banks are 10,000 to 20,000 mAh, which is roughly 37 to 74 Wh, comfortably under the free limit. The ones that cross into approval territory are large laptop banks and camera batteries. If the capacity is printed only in mAh, the math is Wh = (mAh ÷ 1000) × voltage, and most power banks are 3.7 V. A 26,800 mAh bank at 3.7 V is about 99 Wh, right at the edge.
Individual airlines have added their own stricter rules on top of this, and several now announce it at boarding. Check your airline's page before you fly with anything large.
The rest of the electronics list:
- Wall charger with the right plug type, plus a plug adapter for international travel
- Multi-port charger to cut down on blocks
- One long cable (6 ft) beats two short ones, since hotel outlets are never near the bed
- Headphones plus the wired backup, since seatback entertainment often still needs a 3.5 mm jack
- Laptop or tablet in an easily removable spot, since older security lanes still want it out
- Voltage note: most modern chargers handle 100 to 240 V automatically, so an adapter is usually enough and a converter usually isn't. Check the fine print on the brick before you fry a hair dryer.
First Aid and Medication
Keep this small and keep it in your personal item.
The kit that covers 90% of trip problems:
| Item | Why it earns its space |
|---|---|
| Pain reliever (ibuprofen and acetaminophen) | Headache, fever, sore feet |
| Antihistamine | Unexpected allergies, insect bites, sleep |
| Anti-diarrheal and rehydration salts | The single most common travel illness |
| Antacid | Unfamiliar food, late meals |
| Motion sickness tablets | Boats, buses, mountain roads |
| Bandages and blister plasters | New shoes and long walking days |
| Antiseptic wipes | Small cuts |
| Tweezers and small scissors | Splinters, threads, packaging |
| Hydrocortisone cream | Bites and rashes |
| Thermometer | Deciding whether to see a doctor |
Prescription medication, honestly:
Carry every prescription in its original labeled container with your name on it. TSA doesn't require this for domestic screening, but customs officers in other countries frequently do, and a loose bag of unmarked pills is a genuinely bad conversation to have at a border.
For international travel:
- Bring a copy of the prescription or a letter from your doctor with the generic drug name
- Check whether your medication is legal at your destination, because some common medications, including certain ADHD stimulants, strong painkillers, and some cold and sinus medicines, are controlled or banned in specific countries
- Bring enough for the whole trip plus several extra days, since refilling abroad ranges from easy to impossible
- Split the supply between two bags if you're carrying more than one, so a lost bag isn't a lost course of treatment
- Keep temperature-sensitive medication in your personal item with a gel pack, which is allowed even when partially melted
Our travel document checklist covers the prescription paperwork side in more detail, and how long it takes to get a passport matters if your international trip is still in the planning stage.
Packing Tables by Trip Length
Clothing counts, assuming you'll do laundry once on anything over a week. All of this fits the bag-first rule: the numbers below are the carry-on and checked contents, on top of the personal item list.
Weekend (2 to 3 days)
| Item | Count | Notes |
|---|---|---|
| Shirts or tops | 3 | One per day, one is worn |
| Bottoms | 1 to 2 | Wear the bulkier pair |
| Underwear and socks | 4 pairs each | Always pack one extra |
| Sleepwear | 1 | |
| Shoes | 1 worn, 1 packed | Wear the heaviest pair |
| Outer layer | 1 | Worn, not packed |
| Toiletries | Quart bag | Solids cut this in half |
Bag: personal item plus a carry-on. No checked bag. This fits in a backpack alone if you skip the second shoes.
One Week (5 to 8 days)
| Item | Count | Notes |
|---|---|---|
| Shirts or tops | 5 to 6 | Mix layers so tops recombine |
| Bottoms | 2 to 3 | Two pairs cover a week |
| Underwear and socks | 8 pairs each | The item worth overpacking |
| Sleepwear | 1 to 2 | |
| Shoes | 2 total | One walking, one for evenings |
| Outer layers | 2 | One light, one warm |
| Swimwear | 1 to 2 | If relevant |
| Toiletries | Quart bag plus checked extras | |
| Laundry | Optional | A small detergent sheet pack weighs nothing |
Bag: personal item plus a carry-on for most people. A checked bag only if the destination is cold or formal.
Two Weeks and Longer
| Item | Count | Notes |
|---|---|---|
| Shirts or tops | 7 to 8 | Plan one laundry cycle |
| Bottoms | 3 to 4 | |
| Underwear and socks | 10 pairs each | Laundry once, mid-trip |
| Sleepwear | 2 | |
| Shoes | 2 to 3 | Third pair only if the activity demands it |
| Outer layers | 2 to 3 | Layering beats one bulky coat |
| Formal outfit | 1 | Only if you actually have a plan for it |
| Toiletries | Full size in checked | Refill the quart bag from these |
| Laundry supplies | Yes | Detergent sheets and a sink stopper |
Bag: personal item, carry-on, and a checked bag. The math flips around 10 days, because packing 14 days of clothes weighs more than doing laundry once.
Worked Example: One Week in Portugal, Carry-On Only
Two travelers, seven nights, September, one shared carry-on plus a personal item each.
Personal item, traveler one (backpack, 16 L): passport, two cards from different banks, a small amount of local cash, prescription allergy medication in the original bottle, glasses plus prescription, phone, 10,000 mAh power bank (37 Wh, well under the limit, kept at the seat), charging cable, wall block, EU plug adapter, headphones, empty water bottle, two granola bars, one clean shirt and one set of underwear, toothbrush and travel toothpaste, light scarf.
Personal item, traveler two (tote, 14 L): same structure, plus the shared first aid kit and the shared quart bag.
Shared carry-on (22 x 14 x 9 in): 10 tops, 5 bottoms, 14 pairs of underwear and socks, 2 sets of sleepwear, 2 swimsuits, one pair of evening shoes each, two light jackets, one folded day bag, one laundry bag, detergent sheets.
Shared quart bag: sunscreen stick (solid, so it isn't even in the bag), toothpaste tabs (also not in the bag), shampoo bar and conditioner bar (not in the bag), 3 oz face wash, 1.7 oz moisturizer, 1 oz serum, mascara, 2 oz contact solution, small perfume. Five containers in the quart bag, sealed easily.
What the solids swap bought them: the four items that would have filled the bag (shampoo, conditioner, toothpaste, sunscreen) took zero quart-bag space. That's the reason two people fit in one bag instead of paying for a checked bag on both legs.
What went where, tested against the rule: if the carry-on got gate-checked at the door, both travelers still had documents, money, medication, glasses, power, and a clean shirt. Nothing on that list is replaceable in a hurry, and nothing on it was in the bag that could be taken.
Frequently Asked Questions
What are the most important travel essentials to pack?
Passport or ID, payment cards from two different banks, prescription medication in original containers, phone and charger, and one change of clothes. Every one of those belongs in your personal item, because it's the only bag guaranteed not to be separated from you. Everything else on a packing list is replaceable at the destination.
What should I put in my carry on essentials bag?
Clothes, toiletries in a quart bag, a second pair of shoes, and anything you'd like to have but could survive losing for a day. Keep medication, documents, chargers, and valuables out of it, because a carry-on can be gate-checked with almost no warning when the overhead bins fill on a full flight.
How do I pack a toiletries bag for travel?
Start from the 3-1-1 rule: containers of 3.4 oz or less, all fitting in one quart-sized clear bag. Then swap the bulky items to solids, since bar shampoo, solid sunscreen, toothpaste tabs, and stick deodorant aren't liquids and don't use quart-bag space at all. Full-size versions can ride in a checked bag if you have one.
Can I bring a power bank on a plane?
Yes, in your carry-on only, with a maximum of two spare batteries per passenger as of the March 2026 rules. It must stay accessible at your seat rather than in the overhead bin, and you can't charge it or charge from it in flight. Under 100 Wh needs no approval, 100 to 160 Wh needs airline approval in advance, and over 160 Wh isn't allowed at all.
How many outfits should I pack for a week?
Five or six tops and two or three bottoms, chosen so the pieces recombine. Pack eight pairs of underwear and socks, since those are the items where running short is genuinely miserable and they weigh almost nothing. Two pairs of shoes total, with the heaviest pair worn on the plane.
Should I pack medication in my carry-on or checked bag?
Carry-on, and specifically your personal item. Checked bags get delayed, and a delayed bag with your medication in it turns a minor inconvenience into a medical problem. Keep everything in original labeled containers, and if you're carrying a large supply, split it between two bags you're carrying.
What things should I bring on vacation that people usually forget?
A plug adapter for the destination, a long charging cable, an empty water bottle, a folded day bag, backup glasses or contacts, and a small first aid kit. Chargers and adapters are the most commonly forgotten items and the most annoying to replace at airport prices.
Do I really need a checked bag for a one week trip?
Usually not. A week of clothing fits a standard carry-on if you plan around layers and swap your toiletries to solids. A checked bag makes sense for cold-weather trips, formal events, sports gear, or any trip where you're bringing full-size liquids that can't be replaced at the destination.
Turn this into your actual list. The packing list generator builds one for your destination and trip length, the TSA item checker settles anything you're unsure about, and the carry-on size checker confirms the bag fits before you're standing at the gate sizer.
