What to do during a layover: tips for every length of stop

A layover is not dead time — it is a clock you can work with or waste. Under 90 minutes, the only reliable move is staying near your gate. Three to six hours unlocks airport lounges, yoga rooms, and a proper meal. Six hours or more can mean a genuine city excursion if you pick the right airport and leave an adequate return buffer. Here is the exact playbook for each window, including updated 2026 rules for international connections.

Under 90 minutes: stay near your gate and use the time wisely

The only reliable move on a short connection is staying within five minutes of your departure gate. Use your airline's app to monitor real-time gate changes — announcements lag behind app alerts — and grab food at the nearest counter rather than hunting for a distant restaurant. Download any entertainment before you board your originating flight, not at the layover airport, where time and Wi-Fi are both unreliable. A 90-minute stop disappears faster than it looks on a boarding pass.

• Open your airline app the moment you land; gate changes are pushed silently to the app before they hit the PA
• Keep your carry-on organized before landing so you are not repacking at the gate
• Charge your phone at the first available outlet; a dead phone is a problem at any layover length
• Eat closest to your gate — the time cost of walking to a specific restaurant is rarely worth it under 90 minutes

2–4 hours: explore your terminal and consider a lounge

Two to four hours is the sweet spot for a lounge visit: enough time to eat, potentially shower, and return to the gate without rushing. Most major US terminals have both fast-casual and full-service restaurants inside security, with the time difference between them usually under 20 minutes. If you have lounge access through a credit card or status, use the LoungeBuddy app or Priority Pass app to confirm availability in your specific terminal before walking over — not every terminal at a given airport has a participating lounge.

• Lounge day passes cost $59–79 at most US airports; availability is capped so check the app before assuming you can walk in
• Shower slots at busy lounges fill up — tell the front desk immediately on arrival if that is your priority, wait times can hit 30 minutes
• A sit-down restaurant is usually worth the 10–15 extra minutes over fast food on a 3-hour stop; the slower pace reduces stress
• Download a show or playlist now if you did not do it before departure — you will need it on the next leg

4–6 hours: cross terminals and find hidden airport amenities

A four-to-six-hour layover is long enough to leave your arrival terminal and explore the full airport. Most US airports connect terminals via free shuttles or trains — JFK's AirTrain loops all active terminals at no charge, DFW's Skylink connects all five terminals in minutes. This window also makes airport wellness amenities worthwhile. SFO operates three free yoga rooms — at Harvey Milk Terminal 1, Terminal 2, and the International Terminal near Gate E6 — open 24 hours with mats provided. DFW has two free yoga studios in Terminal B and Terminal E, also 24 hours with stretch bands and exercise balls. Seattle-Tacoma and Boston Logan both have designated meditation rooms airside.

• SFO yoga rooms: Harvey Milk T1, T2, and International Terminal near Gate E6 — free, 24 hrs, mats provided (verified via flysfo.com)
• DFW yoga studios: Terminal B near gate D40/B1 and Terminal E near gate E31 — free, 24 hrs, exercise equipment included (verified via kindtraveler.com)
• ORD Terminal 3 Rotunda Mezzanine Level has a yoga room open 6 am–10 pm daily
• Inter-terminal transit is typically free and airside at major hubs: JFK AirTrain, DFW Skylink, ATL underground train, SFO AirTrain
• Some JFK terminal transfers require exiting and re-entering security — factor an extra 30 minutes if switching terminals there

6+ hours: should you leave the airport?

A six-hour or longer layover can justify a city excursion, but only if transit is fast and you build in a 2–3 hour return buffer for security re-screening. The easiest US airports to escape are JFK, BOS, SFO, and DCA. LAX requires a shuttle to the Metro C Line first, adding 20–30 minutes. The rule: if your total layover is under 6 hours, the math rarely works once you factor in transit both ways plus re-clearing security — particularly on international departures, where the buffer should be 3 hours.

• JFK: AirTrain free between terminals; $8.75 to exit at Jamaica Station; E train $3.00 to Manhattan (~50–70 min); LIRR ~20 min; budget 3 hrs before your outbound flight
• BOS: Silver Line free from Terminal A to South Station, then connect to Red/Green/Orange Lines (~30 min total)
• SFO: BART from International Terminal to downtown SF in ~30 min for ~$11 each way
• DCA: Yellow/Blue Metro from Reagan National to downtown DC in ~20–25 min
• Store checked bags at the airport (SmarteCarte or similar) before leaving — dragging luggage through a city adds time and risk
• Budget 2 hours before domestic departures and 3 hours before international when returning to the airport

How to access an airport lounge without flying business class

Lounge access in 2026 is available through more channels than most travelers realize. The simplest one-off option is a day pass bought at the lounge entrance for $59–79. For anyone who flies more than three or four times a year, a credit card that includes Priority Pass membership is a better value. The LoungeBuddy app — now part of American Express Travel — lets you search by airport and terminal, see real-time capacity, and book day passes in advance so you are not turned away at the door. For a deeper look at what each lounge tier offers, see the airport lounge access guide.

• LoungeBuddy app: search by terminal, see capacity, and pre-book — critical at busy airports where walk-up day passes sell out
• Priority Pass covers 1,400+ lounges worldwide; both Chase Sapphire Reserve and Capital One Venture X include it with the card
• Amex Platinum ($695/yr) covers Centurion Lounges and Priority Pass, plus Delta Sky Club when flying Delta

International layover visa rules every US traveler should know in 2026

US citizens generally do not need a transit visa to connect through Europe, the UK, or Canada — but two significant changes took effect in late 2025 and early 2026. The EU launched its Entry and Exit System (EES) on October 12, 2025, replacing passport stamps with biometric scans for non-EU nationals entering Schengen countries; airside connections where you never cross the border are unaffected. The UK now requires a pre-approved Electronic Travel Authorization (ETA) since February 25, 2026, but transit passengers who remain airside and never pass through UK border control are explicitly exempt. The EU's ETIAS pre-authorization is expected in late 2026 and will similarly exempt airside transit passengers.

• UK ETA (active Feb 25, 2026): required for US citizens who enter the UK; explicitly NOT required for airside transit without crossing UK border control (source: travel.state.gov, United Airlines)
• EU EES (active Oct 12, 2025): biometric entry/exit scans replace passport stamps; US citizens remain visa-free for up to 90 days in any 180-day window; airside connections are unaffected
• EU ETIAS (expected Q4 2026): ~€7 fee, 3-year validity once active; NOT required for airside layovers per official EU guidance (source: ricksteves.com, travel-europe.europa.eu)
• Canada: US citizens do NOT need a visa or eTA to fly to or transit through Canada (confirmed via United Airlines international requirements page)
• US airports: there are no international transit zones in the US — every connecting passenger, regardless of nationality, must clear US immigration and customs
