What Should You Do During a Long Layover at a US Hub Airport?

Summary

The steps

1. 1

   Confirm Your Layover Length and Departure Gate

   Before you do anything else, confirm your actual departure time and gate for the next flight. Departure times can shift, gates can change, and a layover that looked like five hours on your booking confirmation can shrink. Check the airline's app, the airport's flight information display system (FIDS), or the airline's website for real-time status.

   Note whether your next flight departs from the same terminal or a different one. At large US hub airports, moving between terminals can require a train, a shuttle bus, or a significant walk - and may require clearing security again if the terminals are not airside-connected. The FAA classifies US commercial airports by hub size under 49 U.S.C. 47102 (definitions) and publishes terminal configuration data in its 5010 Airport Master Record database (faa.gov/airports). Knowing the layout before you wander off saves a stressful scramble later.

   Do this

   Open your airline's app and confirm the current departure time and gate for your next flight.,Check whether your next gate is in the same terminal or a different one.,Set a flight status notification so you are alerted to any gate or time changes.

   Example

   A traveler with a six-hour layover discovers their next flight departs from a different terminal that requires exiting security and re-entering. They budget 90 minutes for the terminal change and security re-screening, leaving four and a half hours for the rest of their layover plan.

   Best practice

   Write down or screenshot your departure gate and time before you leave the gate area. Airport Wi-Fi can be unreliable in some parts of a terminal.
2. 2

   Stow Your Carry-On Bags if You Want to Move Freely

   Dragging a carry-on through a terminal for hours is tiring. Many large US hub airports have luggage storage services operated by third-party providers such as Bounce or airport-specific concessionaires. These services let you drop bags for a per-hour or per-day fee and move through the terminal unencumbered.

   Luggage storage locations vary by airport; check the airport's official website or the provider's app before your layover to confirm availability and location. Locations inside the secure area (past TSA) are more convenient than those in the departures hall if you do not want to clear security twice. TSA security screening is required under 49 U.S.C. Chapter 449, Section 44901 (screening passengers and property) for every person entering the secure area; re-entry after leaving always means a fresh screening, regardless of how recently you last cleared it.

   Do this

   Search the airport's official website for 'luggage storage' before your trip.,If a provider lists a location inside the secure area at your airport, book in advance during busy travel periods.,Keep your personal item (laptop bag, purse) with you even after stowing your carry-on.

   Example

   A traveler with a seven-hour layover drops their carry-on at an airside luggage storage kiosk and spends the afternoon walking the terminal and eating at a sit-down restaurant without wheeling a bag.

   Best practice

   Keep your passport, wallet, phone, charger, and any medication in your personal item, not in the stored bag. You should be able to function fully without the stored bag for the duration of your layover.
3. 3

   Access a Lounge if You Are Eligible

   Airport lounges offer a quieter environment, seating with power outlets, food and beverages, and often showers - a significant upgrade over the main terminal during a long layover. Access options include:

   • Airline status lounges: Available to elite-status members of the operating airline or its alliance partners (Star Alliance, SkyTeam, oneworld). Check your status tier and the lounge's guest policy.
   • Priority Pass: A membership network included with several premium travel credit cards. Priority Pass grants access to a wide network of independent and airline lounges at many US hub airports. Check the Priority Pass app for participating lounges at your specific airport.
   • Amex Centurion Lounges: Available to eligible American Express cardholders at select US airports. Guest fees and cardholder spending thresholds apply; check amextravel.com for current terms.
   • Day passes: Many independent lounges sell day passes at the door or online. Prices vary; check the lounge's website before your trip.

   Lounge availability, capacity, and amenities change. Always verify current access rules directly with the lounge or provider before your trip.

   Do this

   Check your credit cards for Priority Pass or Amex lounge benefits before your trip.,Use the Priority Pass app or the lounge's website to confirm the lounge is open and accepting walk-ins on your travel date.,If purchasing a day pass, consider booking online in advance as some lounges cap walk-in capacity.

   Example

   A traveler with a Priority Pass membership uses the app to find an independent lounge in their terminal, confirms it accepts Priority Pass, and spends two hours eating and working before heading to their gate.

   Best practice

   Arrive at the lounge early in your layover, not at the last minute. Showers, quiet rooms, and seating fill up during peak hours.
4. 4

   Eat a Proper Meal

   Airport dining at large US hub airports has improved significantly. Beyond fast food, most major hubs now have sit-down restaurants, local food concepts, and grab-and-go options with fresh ingredients. A proper meal during a long layover - rather than snacking from a vending machine - supports energy levels and hydration before the next leg of your journey.

   If you are in a lounge, the food and beverage offering may be sufficient. If not, explore the terminal's dining options. At large hubs, different concourses often have different restaurant selections; if your gate allows time, it can be worth walking to a different concourse for a better choice. The airport's official website or its dedicated app typically publishes a dining directory organized by concourse and terminal.

   Do this

   Check the airport's official website or app for a dining directory before your layover.,Sit down for a full meal rather than grazing on snacks if your layover is four hours or longer.,Drink water consistently throughout your layover to offset the dehydrating effects of cabin air.

   Example

   A traveler with a five-hour layover checks the airport's dining map, walks to a concourse with a local restaurant concept, and sits down for a meal - arriving at the next flight noticeably more comfortable than on a previous trip where they ate only packaged snacks.

   Best practice

   Avoid heavy, rich meals and excess alcohol before a long flight. Both can worsen fatigue and discomfort in the cabin.
5. 5

   Rest, Recharge, and Move Your Body

   Long layovers are an opportunity to arrive at your next destination less fatigued. Three practical approaches:

   • Rest: If your airport has sleep pods (such as Minute Suites, available at select US hub airports) or a dedicated quiet zone, use them. If not, look for less-trafficked gate areas away from busy concourses. A neck pillow and eye mask are worth carrying in your personal item.
   • Recharge devices: Locate a power outlet or USB charging station early in your layover, before the seats around them fill up. Many US hub airports have installed charging stations at gate seating, but availability is not universal.
   • Move: Walking the terminal is free and counteracts the stiffness of a long flight. Most large hub airports have walking distances of half a mile or more between concourse ends. Some airports post walking routes or have fitness areas; check the airport's website.

   Do this

   Book a sleep pod in advance if your airport offers them and your layover is overnight or very long.,Locate a power outlet within the first 30 minutes of your layover and charge all devices.,Walk at least one full concourse length during your layover to reduce stiffness before the next flight.

   Example

   A traveler on an overnight layover books a Minute Suites pod (where available) for four hours, sleeps, showers in the lounge, and boards their morning flight feeling rested rather than exhausted.

   Best practice

   Set an alarm if you plan to sleep, with enough buffer time to walk to your gate. Missing a flight because of an unplanned nap is an avoidable and expensive mistake.
6. 6

   Decide Whether to Leave the Airport

   On a domestic itinerary, leaving the airport during a long layover is permitted and can be worthwhile if you are in a city with attractions close to the airport. On an international itinerary, whether you can leave depends on your citizenship, visa status, and whether you have cleared CBP (see the FAQ above).

   Before you leave, confirm:

   1. Your checked bags are checked through to your final destination and you do not need to collect them.
   2. You have a reliable way to get back to the airport (rideshare, train, or taxi) with enough buffer time.
   3. You have budgeted time for TSA security screening on re-entry. Screening is mandated under 49 U.S.C. Section 44901(a) for all passengers and accessible property before boarding; check the airport's live security information or the MyTSA app (iOS and Android, published by the Transportation Security Administration) for current conditions before you leave.
   4. You have your boarding pass and all travel documents with you.

   A general rule: if your layover is under four hours, leaving the airport is usually not worth the risk. If it is six hours or more, and you have a reliable transport option, it can be a genuine enhancement to your trip.

   Do this

   Confirm your bags are checked through before planning to leave the terminal.,Check the MyTSA app or the airport's live security information for current screening conditions before your planned return time.,Leave yourself a buffer of at least 90 minutes between your planned return to the airport and your departure time.

   Example

   A traveler with an eight-hour layover in a city with a major museum 20 minutes from the airport by train takes the train, spends three hours at the museum, returns to the airport, clears TSA, and boards with time to spare.

   Best practice

   Have a backup plan if your transport back to the airport is delayed. Know the next available rideshare or train option and factor it into your buffer time.
7. 7

   Return to Your Gate on Time

   The final step of any layover plan is the simplest and the most important: get back to your gate on time. Set a departure alarm on your phone for the moment you need to start walking toward the gate, factoring in:

   • The distance from your current location to the gate (terminal trains and shuttles add time).
   • Whether you need to clear TSA security again under 49 U.S.C. Section 44901(a).
   • The airline's recommended boarding window (typically 30 to 45 minutes before departure for domestic flights, longer for international).

   Check the flight information display for any gate changes as you walk. Gate changes at large hubs are common, especially for flights that were delayed and then recovered.

   Do this

   Set a phone alarm for the time you need to start moving toward your gate.,Check the flight information display for gate changes as you approach the gate area.,Arrive at the gate before the boarding window closes, not just before departure time.

   Example

   A traveler sets an alarm two hours before their flight, giving time to collect their stored bag, walk to the correct terminal, clear TSA, and reach the gate 40 minutes before departure - well within the boarding window.

   Best practice

   If you are in a lounge, ask the lounge staff whether they have a flight notification service. Some lounges will alert you when your flight is boarding.

Layover vs. Connection: What Is the Difference?

What This Guide Does Not Cover

FAQ

Can I leave the airport during a layover on a domestic itinerary?

Yes. On a domestic itinerary you can exit the airport during a layover, but you must clear TSA security screening again when you return. Budget enough time for the security line, the walk to your gate, and unexpected delays. TSA recommends checking the airport's live security wait information via the MyTSA app before you go. If your bags are checked through to your final destination, you do not need to collect them.

Can I leave the airport during a layover on an international itinerary?

It depends on your citizenship, visa status, and whether you have already cleared US Customs and Border Protection. If you arrived on an international flight and have not yet cleared CBP, you generally cannot exit the federal inspection area. If you have cleared customs and hold valid US entry documents, you can exit the building, but you must clear TSA security again to re-enter the terminal. Verify your specific situation with CBP or your airline before planning to leave.

How do I access an airport lounge if I do not have airline status or a first-class ticket?

Several options exist regardless of ticket class. A Priority Pass membership (included with several premium travel credit cards) grants access to a network of independent and airline lounges at many US hub airports. Some lounges sell day passes at the door or online. The Amex Centurion Lounge network is open to eligible American Express cardholders. Lounge availability, pricing, and guest policies vary by location; check the lounge's website or the Priority Pass app before your trip.

Is there somewhere to sleep at a US hub airport during a long overnight layover?

Some US hub airports have dedicated rest areas, sleep pods (such as those operated by Minute Suites at select locations), or quiet zones where travelers can rest. Standard airport seating is always available, though comfort varies. Availability of paid sleep options is not universal; check the official website of the specific airport for current amenities. Airside hotels connected directly to some terminals are another option for very long layovers.

What should I do if my layover unexpectedly becomes very long due to a delay?

First, confirm your new departure time with your airline via the app, the airline's customer service desk, or the airport's flight information displays. If the delay is significant, ask the airline about meal vouchers or accommodation - carriers have different policies depending on whether the delay is within their control. Keep notifications turned on for your flight so you do not miss a gate change or an earlier departure if the delay shortens.
