Travel · THE NO-PANIC PLAN
Build an air-travel packing checklist that fits the trip
Good packing starts with the itinerary and current rules for the exact airline and destination, then sorts each item into the right bag. A generic list can miss trip length, weather, medicine restrictions, cabin dimensions or battery safety. This guide is for air travel departing the United States; TSA screening, FAA dangerous-goods and airline baggage rules can change, and destination import rules may be different.
MISSION Help a U.S.-origin air traveler build a trip-specific packing list, separate cabin and checked items, and verify current airline, TSA, FAA and destination requirements before departure.

YOUR CHECKLIST, WITH FEWER DRAMATIC SIGHES
One step at a time.
Follow the order below. If a step names a Nirmion tool, its link is right there with it.
- 01
Gather the trip details and the exact airline baggage allowance
Write down departure/return dates, number of days, destinations and connections, weather forecast, planned activities, access to laundry, mobility or accessibility needs and who is sharing each bag. Open the operating airline's current baggage page for each flight segment and record the permitted carry-on/personal-item size, weight if applicable, checked-bag allowance, fees and gate-check rules; partner flights can have different limits. Keep the ticket and booking reference in your private travel records, not in a public checklist. The Packing List Generator (tool 35039) can create a first list from the trip details, but it cannot retrieve your airline's current allowance, know what the destination permits, or determine whether an item is safe to fly with.
- 02
Check destination entry, health and medication requirements
For international trips, read the destination's official entry/exit guidance, passport/visa requirements and local rules for medicines or restricted goods before deciding what to pack. U.S. Department of State guidance warns that some medicines legal in the United States are restricted abroad; CDC says to check destination health guidance, carry needed medicines and keep them in original labeled containers. Ask your clinician or pharmacist about medical supplies, temperature control, dose timing and an appropriate travel quantity; do not change treatment based on a packing list. The Medical Travel Checklist (tool 12025) can organize non-sensitive health-kit reminders if relevant, but do not enter diagnoses, prescription identifiers or private medical records. Confirm whether required documents may be digital or must be printed.
- 03
Sort each item using TSA screening and FAA baggage rules
For every uncertain item, search TSA's current What Can I Bring list for checkpoint treatment, then check FAA PackSafe for hazardous-material rules that apply to carry-on and checked baggage; a TSA screening answer does not by itself settle airline or destination restrictions. Pay special attention to spare lithium batteries and power banks, which FAA generally requires passengers to keep in the cabin, and check the watt-hour limits and airline approval rules for larger batteries. If a carry-on is gate-checked, remove spare batteries and battery-powered devices that must stay with you. Separate items into cabin bag, checked bag and leave at home; for an item not listed, contact TSA, FAA or the carrier instead of assuming it is allowed.
- 04
Create a lean list and pack essentials where you can reach them
Use the Packing List Generator to make a base checklist, then edit quantities for actual days, weather, activities, laundry and shared items. Mark must-have documents, glasses/hearing aids, chargers, essential medication and a change of clothes as high priority; where appropriate, keep critical items in the cabin bag so a delayed checked bag does not strand you. Follow the clinician's advice and destination rules for prescription medicine, and follow FAA/TSA requirements for liquids, batteries, medical devices and other regulated items. Pack heavier items where your airline permits them and leave room for items that must be removed at screening. The tool is a list organizer, not a legal or aviation clearance system, so record the source and check date for any item-specific rule.
- 05
Do a departure-day audit and recheck changes before travel
Before closing each bag, check the airline's latest size/weight allowance, the TSA list for items that may trigger screening, and FAA PackSafe for batteries, smart luggage and other dangerous goods. Confirm destination entry and medicine requirements again if travel is international, the itinerary changed or a rule was flagged for review. Weigh and measure bags, make sure names and contact details on luggage labels do not expose unnecessary personal information, and verify that boarding/entry documents are accessible in the format required. If your carry-on may be gate-checked, keep spare batteries and essential medication with you. Refresh the checklist when the route, airline, season, bag or health needs change; screening officers and airline staff make final item decisions.
