Why a Pre-Flight Checklist Matters

Even experienced travelers occasionally show up at the airport missing something essential — an expired ID, a forgotten charger, or a medication left on the bathroom counter. The gap between a smooth departure and a stressful one is rarely about bad luck; it's usually about skipping a structured review at home.

This checklist is designed to cover the items that matter most: documents, carry-on compliance, devices, health supplies, and day-of logistics. Work through it the evening before your flight and again on the morning of departure. For a broader view of everything to confirm before any trip, see the Pre-Trip Checklist that covers bookings, home arrangements, and health prep well in advance of travel day.

Documents and Identity

Confirm your government-issued ID is REAL ID-compliant (for domestic US flights) or that your passport is valid for at least six months beyond your return date. Must
Check that any required visas are in place and that entry requirements for your destination haven't changed. Must
Save a digital copy of your passport, visa, and travel insurance to a secure cloud location or email it to yourself. Should
Print or download a physical or offline backup of your boarding pass in case airport Wi-Fi is unreliable. Should

Boarding and Flight Status

Confirm your flight status, gate number, and departure time the evening before and again on the morning of travel. Must
Ensure your boarding pass is accessible — either printed or loaded in your airline's app — before you leave home. Must
Check whether your airline requires check-in to be completed online in advance to avoid fees or seat reassignment. Should

Carry-On and Liquids Compliance

Place all liquids, aerosols, and gels in containers of 3.4 oz (100 ml) or less, packed in a single quart-sized clear zip-top bag. Must
Remove laptops, tablets, and large electronics so they can be placed in a separate security bin without unpacking your entire bag. Must
Check that no prohibited items — such as sharp objects or oversized power banks — are in your carry-on. Must
Wear or pack footwear that is easy to remove at the security checkpoint. Nice to have

Devices and Power

Charge your phone, laptop, tablet, and any wireless earbuds fully the night before departure. Must
Pack charging cables and any adapters needed for your destination in an accessible pocket of your carry-on. Must
Bring a portable battery pack (power bank) to maintain device charge during long layovers or delays. Should
Download offline maps, entertainment, and any documents you may need during the flight before boarding. Should

Medications and Health

Pack all prescription medications in your carry-on in their original labeled containers. Must
Bring a supply that covers your trip plus at least two to three extra days in case of travel disruptions. Must
Separate liquid medications from your 3-1-1 liquids bag and be prepared to declare them at the security checkpoint. Should
Pack a small over-the-counter travel kit with items such as pain relievers, antacids, and antihistamines for common in-flight discomforts. Nice to have

Day-Of Logistics

Confirm your transportation to the airport and factor in extra time for traffic, parking, or shuttle delays. Must
Arrive at the airport at least 90 minutes before a domestic flight and at least 3 hours before an international departure. Must
Notify your bank or credit card provider of your travel dates and destination to avoid fraud alerts blocking your card abroad. Should

What You'll Need to Work Through This Checklist

Most items on this checklist require nothing more than the documents and gear you're already packing. A few tools help you verify digital items or stay organized at the airport.

Required

Airline Mobile App

Used to access your mobile boarding pass, check real-time flight status, and receive gate change notifications.

Required

TSA Website (tsa.gov)

Used to verify current rules for carry-on items, liquids, and prohibited items before packing.

Optional

Secure Cloud Storage (e.g., a password-protected email account)

Used to store digital backups of your passport, visa, and insurance documents accessible from any device.

Optional

Portable Battery Pack (Power Bank)

Used to recharge devices during long waits, layovers, or when airport outlets are unavailable.

Documents and Identity

Document problems are among the most common — and most avoidable — causes of travel disruption. For domestic US flights, a REAL ID-compliant driver's license or state ID is generally required; a passport is always accepted. For international travel, ensure your passport has at least six months of validity beyond your return date, as many countries enforce this rule at the border.

See the Documents Every International Traveller Should Have in Order guide for a detailed breakdown of visas, entry requirements, and backup documentation strategies.

Expired or Non-REAL ID Documents Will Deny Boarding

Starting May 7, 2025, the TSA requires a REAL ID-compliant driver's license, passport, or other accepted identification for domestic US flights. Non-compliant IDs will not be accepted at security checkpoints. Check the REAL ID star marking on your license and verify your passport's expiration date well in advance of your travel date.

Carry-On Compliance and Security Prep

Airport security is faster and less stressful when your bag is already organized before you reach the checkpoint. The TSA's 3-1-1 rule governs liquids in carry-on bags: containers must hold 3.4 ounces (100 ml) or less, all must fit in one quart-sized clear zip-top bag, and one bag per passenger is allowed. Full-size containers — even if mostly empty — will not clear security.

Electronics larger than a cell phone (laptops, tablets, e-readers) must come out of your bag and go into a separate bin. Wearing shoes that slip off easily and avoiding excessive metal jewelry or belt buckles will help you move through the line smoothly.

TSA Rules Change — Always Verify Before You Pack

Prohibited items and carry-on rules can be updated by the TSA at any time. What was permitted on a previous trip may not be allowed today. Always check the official TSA website (tsa.gov) or the "What Can I Bring?" tool before packing, particularly for items like power banks, aerosols, food items, or sporting equipment.

Medications and Health Supplies

Prescription medications should travel in their original labeled containers where possible. Liquid medications are generally exempt from the 3-1-1 limit but must be declared separately at the security checkpoint. If you use medical devices such as a CPAP machine or insulin pump, notify the TSA officer before screening begins.

Always pack enough medication to cover your trip plus a few extra days in case of delays. Keep medications in your carry-on, never checked luggage, in case your bag is delayed or lost.
