Skip the “bring a sarong, it has 40 uses” lists. These are the eight habits that separate people who breeze through the airport from people crouched next to a scale, unzipping.
The single biggest source of airport stress is a bag that turns out to be over the limit at the counter. Use a $10 luggage scale before you leave the house — carry-ons are usually capped at 7–10 kg (15–22 lb) and checked bags at 23 kg (50 lb). If you're close, move the heaviest items into the personal item you'll bring on board.
For a 7-day trip, pack 5 tops, 4 bottoms, 3 pairs of shoes (walking, dressier, one for the pool/shower), 2 layers (a light sweater and a rain shell), and 1 hat. Roll everything and pick a two- or three-color palette so anything mixes with anything. It sounds austere; it never is.
Your carry-on should hold a full change of clothes, all medications, chargers, one full outfit for the next day, and any valuables. Airlines misplace roughly 6–8 bags per 1,000 passengers — small odds, but a ruined first day of a trip is a big cost for 15 minutes of packing.
Passport, ID, insurance card, printed hotel and flight confirmations, and a paper copy of your itinerary all go in a single zippered pouch — plus a photo of each on your phone. Border agents, hotels, and rental desks still ask for paper more often than you'd expect.
Skip the multi-plug travel kits. One universal adapter with USB-C fast charging plus a 10,000 mAh power bank covers phones, watches, headphones, and a laptop through most travel days. Charge the power bank the night before every travel day.
Ibuprofen, antihistamine, motion-sickness pills, blister plasters, rehydration salts, and any prescriptions in their original packaging. Add a small tube of hydrocortisone cream for bites and heat rash. This kit fits in a sandwich bag and prevents about 90% of "we need to find a pharmacy" detours.
Never keep every card, every bill, and your passport in the same pocket. Split: one card + some cash in your day bag, a backup card + emergency cash in your main luggage, and a small stash in a completely different spot (a shoe, a book, the hotel safe). Losing a wallet becomes annoying instead of trip-ending.
You will bring things home. Souvenirs, a bottle of wine, a jacket you didn't expect to buy. Packing to 100% capacity guarantees a return trip with an extra tote bag on your shoulder or a $75 overweight fee. Start with room to grow.
One list for what stays with you, one for what goes in the hold. Print it, screenshot it, or tick it off in WayCrumb next to your trip.
Packing is one step. These guides cover the rest.

Weigh your bag before you leave, pack a carry-on that could stand in for a lost checked bag, keep documents in one pouch, and leave about 15% of your luggage empty for things you bring home. Those four habits prevent most first-time packing mistakes.
Use the 5-4-3-2-1 clothing rule (5 tops, 4 bottoms, 3 shoes, 2 layers, 1 hat) in a two- or three-color palette, roll every garment, and use packing cubes to compress. Wear your bulkiest layer and heaviest shoes on the plane. Most people can do 7–10 days in a proper carry-on.
Passport, wallet, phone, chargers, medications, headphones, a full change of clothes, snacks, and any valuables. If your checked bag is delayed, this bag should carry you comfortably for 24 hours.
Universal power adapter, phone charging cable, prescription refills, a copy of travel insurance, sunscreen, blister plasters, and a pen. Build a permanent packing checklist so these never disappear again.
Commit to a color palette so every top matches every bottom, choose fabrics that dry overnight (merino wool, technical synthetics), and plan to wash mid-trip once. Two loads of hostel-sink laundry beats hauling a giant suitcase across cobblestones.
Carry on for trips of 10 days or less, tight connections, or destinations where lost luggage would ruin the first days (small islands, remote regions). Check a bag for longer trips, when you're packing gear (ski, dive, camping), or when you're flying with kids and every hand is already full.
Save this checklist to your next WayCrumb trip. Tick items off as you pack, share it with your travel partner, and keep it with the itinerary — not lost in a notes app.
