# How much time do you need for a connecting flight? Rules of thumb > How much time do you need for a connecting flight? Airline minimums at big hubs, one ticket vs. separate tickets, US customs, and how much buffer to plan. - URL: https://traypass.app/blog/how-much-time-do-you-need-for-a-connecting-flight - By: Gonzalo Fuentes, Traypass - 2026-10-28 - [es](https://traypass.app/es/blog/cuanto-tiempo-de-escala-es-recomendable) · [fr](https://traypass.app/fr/blog/combien-de-temps-pour-une-correspondance-avion) · [de](https://traypass.app/de/blog/wie-viel-zeit-zum-umsteigen-am-flughafen) · [it](https://traypass.app/it/blog/quanto-tempo-serve-per-uno-scalo) · [ja](https://traypass.app/ja/blog/connecting-flight-time) ## In short - On one ticket, the airline's **minimum connection time** is the floor: 40 minutes at Amsterdam, 60 at Frankfurt. It is what the airline will sell, not what is comfortable. - Plan on **about 90 minutes** in Europe, more if you cross a border or change terminals. Paris Aéroport recommends about 90 minutes inside Terminal 2 at Charles de Gaulle. - When you fly into the US and connect, you clear immigration and customs at the first US airport, recheck your bags, and go through TSA again: Seattle-Tacoma asks for **120 to 180 minutes**. - On **separate tickets**, nobody rebooks you if you miss the second flight. British Airways recommends at least **4 hours** at Heathrow. - Changing airports means the transfer plus a whole new check-in: about 3 hours by bus from Stansted to Gatwick, 60 to 90 minutes from Charles de Gaulle to Orly. How much time do you need for a connecting flight? On one ticket, the airline’s minimum is the floor, between 40 and 90 minutes at Europe’s big hubs. What you should plan on is more: about 90 minutes in Europe, 2 to 3 hours when you land in the US and fly on, and 4 hours or more on separate tickets. - One ticket in Europe: 90 minParis Aéroport’s advice inside CDG Terminal 2 - Landing in the US: 2–3 hImmigration, customs, bags, and TSA again - Separate tickets: 4 hBritish Airways’ advice at Heathrow ## How much time you need, by situation It depends on three things: whether both flights are on one ticket, whether you cross a border, and whether you change terminals or airports. The table puts the airlines’ minimums next to what airports and airlines recommend. Situation Airline’s minimum Plan on One ticket, inside Schengen 40–60 min About 90 min One ticket, crossing a border in Europe 50–80 min 90–120 min Landing in the US, flying on — 2–3 h Separate tickets, same airport None At least 4 h Changing airports 3 h (JAL, Tokyo) 4 h plus the transfer Figures checked on October 25, 2026, on the airlines’ and airports’ own pages; Air France’s minimums at Charles de Gaulle come from travel-trade reports. ## What a minimum connection time is A minimum connection time is the shortest gap between two flights that an airline will sell you on one ticket at a given airport. It changes with the airport, the airline, the terminals, and whether you cross a border. It is a floor, not advice: Japan Airlines says meeting it does not guarantee the connection when there are delays. Airports often recommend more: Paris Aéroport suggests about 90 minutes between two flights inside Terminal 2 at Charles de Gaulle, while Air France is reported to sell some connections there with 60 minutes. ![A walkway with moving sidewalks in Terminal 2E at Paris-Charles de Gaulle, beside a wall that reads Paris vous aime](/_astro/photo-cdg.BRRem8tu_b6fJk.webp)[John Cameron · Unsplash](https://unsplash.com/photos/nWMc1QZwgis?utm_source=traypass&utm_medium=referral) ## Minimum connection times at big airports They range from 40 minutes inside Schengen at Amsterdam to about 90 between terminals at Heathrow, and US airports speak in hours. At Heathrow, every connecting passenger goes through security again. At Charles de Gaulle, Air France’s Short Connection Pass gives priority at security and border control to passengers with under an hour between flights, a delayed first flight, or long lines. Airport Time What it is Amsterdam Schiphol 40 / 50 min KLM’s minimum, Schengen / non-Schengen Frankfurt 60 min Lufthansa’s minimum since March 30, 2025 Paris-Charles de Gaulle About 90 min Paris Aéroport’s advice inside Terminal 2 London Heathrow About 90 min British Airways, Terminal 3 to 5 Seattle-Tacoma 120–180 min The airport’s advice for international arrivals Chicago O’Hare Up to 2 h Immigration and customs alone, rarely longer ## One ticket or separate tickets: who rebooks you On one booking, if the first flight is late and you miss the second, the airline puts you on another flight. On separate tickets, often called a self-transfer, nobody does: the second airline owes you nothing, and you buy a new ticket. The bags follow the same rule. On one booking, they usually go through to your final destination. On separate bookings, you collect them, check in again, and go through security again. That is why British Airways recommends **at least 4 hours** between separate tickets at Heathrow. On one booking under EU rules (any flight from an EU airport, and flights into the EU on an EU airline), a missed connection that gets you to your final destination more than 3 hours late also entitles you to compensation, unless the delay was caused by extraordinary circumstances or you were held up at security: Distance to your final destination Compensation Up to 1,500 km (about 930 miles) €250 1,500–3,500 km (about 930–2,175 miles), or any longer flight within the EU €400 Over 3,500 km (about 2,175 miles) €600 On separate tickets, EU rules can still cover a delay on the first flight, but not the second flight you missed. Flights within the US have no EU-style compensation law. ## Passport control when you connect in Europe A connection between two Schengen countries has no passport check. Crossing the Schengen border does, so flying from the US, you get one at the first Schengen airport on the way in and at the last one on the way out, and the line is part of your connection time. Since April 10, 2026, the Entry/Exit System (EES) registers travelers from outside the EU, Americans included, with fingerprints and a facial image at that border. Long lines were reported in its first weeks. ETIAS, the EU’s travel authorization, is not in operation yet: you don’t need it. ![A plane at its jet bridge at Helsinki Airport at night, seen from inside the terminal](/_astro/photo-helsinki.DAwe5nUu_2bAGuC.webp)[Majkl Velner · Unsplash](https://unsplash.com/photos/0JWOsrI0lTI?utm_source=traypass&utm_medium=referral) The UK is not in Schengen. Connecting airside at Heathrow, you don’t go through UK immigration. Changing airports in London is different: you enter the UK, so you need an Electronic Travel Authorisation (ETA), £20 (about $27), even if you only cross the city. ## Connecting through a US airport You clear immigration and customs at the first US airport you land at, even when your final stop is another US city. You collect your checked bags, take them through customs, recheck them with the airline, and go through TSA security again. Seattle-Tacoma asks for **at least 120 to 180 minutes** between flights. ![The lit walkway with moving sidewalks between concourses B and C in Terminal 1 at Chicago O'Hare, glowing in changing colors](/_astro/photo-ohare.BJj5_7tn_Z1SPTG1.webp)[Silvia Fang · Unsplash](https://unsplash.com/photos/q28RrU7EXis?utm_source=traypass&utm_medium=referral) At Chicago O’Hare, United and American recheck bags right after customs; with other airlines, you leave Terminal 5 to do it. Immigration there rarely takes more than two hours. A few airports abroad, such as Dublin and Toronto, have US preclearance: you go through US immigration before you board and land as a domestic passenger. If someone traveling with you holds a passport from a Visa Waiver Program country, they need an ESTA even just to change planes in the US: $40.62. ## Changing airports: London, Paris, Tokyo Count the trip across town plus a whole new check-in. You collect your bags at the first airport and check them in again at the second, and the trip between them is at your expense. Change How Time Fare Stansted → Gatwick Bus, changing in London About 3 h — Stansted → Gatwick Train via Liverpool Street and Victoria 1 h 15 min + crossing London — Charles de Gaulle → Orly RER B and Orlyval 60–90 min €14 Charles de Gaulle → Orly Taxi 35 min–1 h 40 min From about €100 Narita → Haneda Train 90–115 min ¥1,760–3,080 Narita → Haneda Airport Limousine bus 65–85 min ¥3,600 Even on one ticket, Japan Airlines asks for at least 3 hours between Haneda and Narita. In London, add UK border control at the first airport and the ETA. ![An easyJet Airbus A319 waiting by the runway at London Gatwick](/_astro/photo-gatwick.yH0VhW4V_Z25negc.webp)[Neil Mewes · Unsplash](https://unsplash.com/photos/zOzOb7ei3b4?utm_source=traypass&utm_medium=referral) ## How tight is too tight Under 45 minutes, you will be running; under 90, a late first flight leaves you no room; and if you change airports, anything under 4 hours is tight. Those are the lines Traypass draws when you add your flights, and what it shows under the first one: - Under 45 minutes at the same airport: **Tight connection**. - Between 45 and 90 minutes: **Not much room if the first leg runs late**. - A different airport for the next flight: **You change airport**, with both codes, counted as tight under 4 hours. - Different confirmation codes on the two flights: **Separate bookings**. These are Traypass’s warnings, not airline rules. In this sample trip to Tokyo, both Finnair flights are on one booking, with 2 hours 5 minutes in Helsinki, so the line under the flight has nothing to warn about. ![A trip called Tokyo & Kyoto in Traypass, December 16 to 27, for Daniel and Beatriz: Finnair AY 1552 from Madrid at 10:05 to Helsinki at 15:40, on time, terminal 4, gate 12, seat 23A, 4h 35m in the air, and under it, 2h 5m in Helsinki, with no warning](/_astro/cx-tokyo-l.Be7Gnzap_Z2t9JaJ.webp) ## Two tickets, two airports Two tickets and two airports make the riskiest connection there is. In this sample trip to Reykjavík, a Ryanair flight lands at Stansted at 8:10 a.m., and an easyJet flight leaves from Gatwick’s North Terminal at 11:40 a.m., on another booking. Traypass flags both problems at once: you change airports, and the bookings are separate. Of the 3 hours 30 minutes, the bus across London takes about 3, leaving about half an hour for UK border control at Stansted, then bag drop and security at Gatwick. If Ryanair lands late, easyJet owes you nothing. The fix is a later flight from Gatwick, or a route sold on one ticket. ![A trip called Reykjavík on a budget in Traypass, November 15 to 21, for Daniel and Pablo: Ryanair FR 8352 from Madrid at 06:30 to London Stansted at 08:10, seat 3B, and under it, 3h 30m in London, leaves from Terminal N, You change airport: STN → LGW, Separate bookings](/_astro/cx-reykjavik-l.BFEq-fhb_Z26I2LU.webp) Traypass shows each connection between its two flights as soon as both are on the trip, and its [flight alerts](/flight-alerts) tell you when the first one is running late. Keep the ETA or ESTA with your passport in [travel documents](/travel-documents).

Inside Europe, on one ticket, often yes: it is at or above the minimum at Amsterdam and Frankfurt. But Paris Aéroport recommends about 90 minutes inside Terminal 2 at Charles de Gaulle, and when you land in the US from abroad, an hour is too little: Seattle-Tacoma asks for 120 to 180 minutes. ### Is 45 minutes enough for a connection? Only on one ticket, at an airport that allows it, and with nothing going wrong. Of the big hubs compared here, only Amsterdam has a lower minimum (40 minutes inside Schengen). If the airline sold it to you as one booking, it rebooks you if you miss it. ### What happens if I miss a connecting flight on one ticket? The airline puts you on another flight. If the trip falls under EU rules and you reach your final destination more than 3 hours late, you may also be owed €250 to €600, unless the delay was caused by extraordinary circumstances or you were held up at security. ### Do I need to collect my bags when I connect? On one booking, your bags usually go through to your final destination. On separate bookings, you collect them and check them in again. Flying into the US, you collect them at the first US airport even on one ticket, clear customs, and recheck them. ### Do I go through passport control when I connect in Europe? Only when you cross the Schengen border. Flying from the US, you get your passport checked at the first Schengen airport, and since April 10, 2026, the Entry/Exit System records your fingerprints and a photo there. Connections between two Schengen countries have no passport check. ### How much time do I need between flights on separate tickets? At least 4 hours at the same airport, which is what British Airways recommends at Heathrow. If the second flight leaves from another airport in the same city, add the trip across town and a whole new check-in. --- Plan this trip in Traypass.
