Layovers: how long you need and what to do
Same ticket and same terminal: 90 minutes is enough. Self-transfer, terminal change or baggage reclaim: allow 3 hours. Airport change or a city run: 6 hours minimum, 8 to be safe.

Applies to
How much connection time a self-transfer, a terminal change or an airport change really needs, when a long layover is worth leaving the airport for, and what to do when a delay eats your buffer.
Key facts
- Same ticket, same terminal
- 90 minutes is a comfortable minimum; 60 works at small airports with no queue
- Same ticket, terminal change
- 2 hours; add 30 minutes at large hubs with a train between terminals
- Self-transfer (two separate tickets)
- 3 hours minimum, 4 if you must collect and re-check bags
- Airport change in the same city
- 4 hours plus the transfer time; 6 hours is the safe figure
- Leaving the airport
- Only worth it above 6 hours; you need 2 hours back at the gate
- Missed connection on one ticket
- The airline rebooks you; on separate tickets you pay for a new flight
- Visa riskcheck
- Leaving the transit area can require a visa even for a few hours

The short answer
The time you need depends on one thing above all: whether your whole journey is on a single ticket. If it is, the airline is responsible for getting you to the final destination, and a 90-minute connection at most airports is enough. If it is not, you are your own ground handler, and the buffer has to cover queues, baggage and a possible rebooking.
Work from the tightest case. A same-ticket, same-terminal connection at a mid-size airport needs about 90 minutes. Add an hour if you change terminals, add two hours if you must collect bags and check in again, and add three or more if the second flight leaves from a different airport in the same city.
For anything under 90 minutes on separate tickets, do not book it. The saving on the cheap leg is usually smaller than one replacement fare.
| Situation | Minimum buffer | Comfortable buffer |
|---|---|---|
| Same ticket, same terminal | 60 min | 90 min |
| Same ticket, terminal change | 90 min | 2 h |
| Separate tickets, hand baggage only | 2 h | 3 h |
| Separate tickets, checked bags | 3 h | 4 h |
| Different airport in the same city | 4 h | 6 h |
| Leaving the airport to see the city | 6 h | 8 h |
Add 30 to 60 minutes at very large hubs, during holiday peaks, or if you need a visa check or a shuttle bus between terminals.
Do
- Check whether the two flights share one booking reference before you buy anything.
- Screenshot your booking, gate and terminal before you fly; airport wifi is unreliable when you need it most.
Who this applies to
This page is for anyone changing planes, which is most long-haul travellers at some point. The rules differ by passport and by ticket type, so read the row that matches you.
One ticket, one airline group. The airline protects the connection. If the first flight is late, they rebook you on the next available seat at no cost, and often provide a hotel if the delay is overnight. Your buffer can be shorter.
Separate tickets, often called a self-transfer. Budget carriers and some online travel agents sell these. The two flights have no legal link. If the first is late, the second is simply missed, and the replacement fare is yours. Your buffer must be longer, and travel insurance may or may not cover it.
Passport and visa position. If you hold a passport that needs a visa for the transit country, you may be confined to the international transit area, or you may need a transit visa even to change terminals. This is the single most common reason a planned city stop fails. Check the destination country's immigration authority before booking, not after.
Checked bags. If the bags are through-checked to the final destination, you stay airside and the buffer is short. If you must collect them, clear immigration and check in again, you are effectively starting a new journey and need the full self-transfer buffer.
Watch out
- A transit visa is not the same as a tourist visa, and not every country offers one at the airport.
- Some countries require you to clear immigration even when you never leave the terminal building.

How to plan a layover, step by step
Step 1. Identify the ticket type. One booking reference covering both flights means a protected connection. Two references mean self-transfer. Write this down before you compare prices, because it changes the whole calculation.
Step 2. Find the real transfer time. Look at the airport's own website for the terminal layout and whether a train, bus or walk connects them. Some hubs put international arrivals and domestic departures in buildings 15 minutes apart by shuttle; others are one corridor.
Step 3. Add the fixed costs. Immigration and security can take 20 minutes at a quiet hour and 90 at a peak. Baggage reclaim is usually 20 to 40 minutes after a long-haul arrival. Bag drop and check-in close 45 to 60 minutes before departure on most airlines, and low-cost carriers often close earlier.
Step 4. Check the visa rule for your passport. If you cannot leave the transit area, a long layover is a wait, not an outing. If you can, note whether the airport has a transit hotel or a left-luggage desk.
Step 5. Decide whether to leave. Use the rule of thumb: you need about two hours back at the airport before departure, plus the round trip to the city. If the layover is under six hours, stay airside.
Step 6. Protect the plan. Buy travel insurance that covers missed connections, keep both bookings on one screen, and know the airline's delay policy before you need it.
| Step | What to check | Where to check it |
|---|---|---|
| 1. Ticket type | One reference or two | Your booking confirmation |
| 2. Transfer time | Terminals, shuttle, walking time | Airport official website |
| 3. Fixed costs | Immigration, security, bag cut-off | Airline and airport sites |
| 4. Visa rule | Transit visa needed or not | Destination immigration authority |
| 5. Leave or stay | Round trip plus 2 h back | Airport transfer apps, rail sites |
| 6. Protection | Missed-connection cover | Your insurer's policy wording |
Do
- Airline apps push gate changes faster than terminal screens.
- If the first flight is delayed, tell the airline desk before you land if you can; rebooking queues are shorter at the departure gate than at the transfer desk.
What a layover costs and how long it takes
A layover itself is free. What costs money is the choice you make inside it: a lounge pass, a transit hotel, a left-luggage locker, a taxi into town, or a replacement ticket after a missed connection.
Airside, the cheap options are a seat near the gate, a shower in a pay-per-use facility, or a day room at an airport hotel. Prices vary widely by airport and are best treated as 2026 estimates: a lounge day pass commonly runs USD 30 to 60, a transit hotel room for a few hours USD 60 to 150, and a left-luggage locker a few dollars per bag per day.
Leaving the airport adds transport. A train or metro into a city centre is usually the cheapest and most predictable, often USD 5 to 15 each way at major hubs. A taxi is faster door to door but can be USD 30 to 70 each way in expensive cities, and traffic can double the time.
The real cost of a missed connection is the replacement fare. On a self-transfer, a same-day walk-up ticket can be several times the price you paid months earlier. That is the number to weigh against the saving from booking separate tickets.
| Option | Typical cost (2026 estimate) | Time cost |
|---|---|---|
| Stay at the gate | 0 | 0 |
| Lounge day pass | USD 30-60 | 10 min to reach |
| Transit hotel, few hours | USD 60-150 | 15-30 min to reach |
| Left luggage | A few USD per bag per day | 10-20 min |
| Train or metro to city | USD 5-15 each way | 30-60 min each way |
| Taxi to city | USD 30-70 each way | 20-60 min each way |
| Missed self-transfer flight | Full new fare | Hours to days |
Costs are 2026 estimates and vary by airport and city; check the airport's own site for current facilities.
Exceptions and traps
Overnight layovers. If the connection is the next morning, you usually need a hotel. Some airlines on a single ticket provide one; most do not, and low-cost carriers almost never do. Book your own room near the airport rather than in the city centre, and confirm the airport is open overnight, because some close their secure areas.
Airport changes. A few cities spread their airports far apart, and the transfer can take 60 to 120 minutes by road or rail. Treat an airport change as a separate journey with its own buffer, and never book one with less than four hours between landing and the next departure.
Visa and immigration traps. Some countries require a transit visa for certain nationalities even when you stay airside. Others require everyone to clear immigration and re-clear security. Check the destination's immigration authority, and carry printed proof of your onward flight.
Baggage rules. On separate tickets, the first airline has no obligation to check bags through to the second. Even on one ticket, some low-cost carriers make you collect and re-check. Confirm at check-in rather than assuming.
Delays and strikes. Weather, air traffic control and strikes can wipe out any buffer. If a delay is the airline's fault on a single ticket, you are entitled to rebooking; in the EU and UK, compensation rules may also apply. On separate tickets, your only protection is your own insurance and your buffer.
Watch out
- Do not plan a city visit on a layover under six hours; the return trip and security will consume it.
- Never leave bags unattended in a terminal, and keep passports and medication with you.
Comparing your options
The table below puts the three common layover shapes side by side. Use it to decide before you book, not after.
The pattern is consistent: the cheaper the ticket structure, the more buffer you must buy with your own time. A protected connection is worth real money when the alternative is a self-transfer with a two-hour gap.
| Shape | Risk | Buffer to allow | Who pays if you miss it |
|---|---|---|---|
| One ticket, same terminal | Low | 90 min | Airline rebooks you |
| One ticket, terminal change | Medium | 2 h | Airline rebooks you |
| Self-transfer, hand baggage | High | 3 h | You |
| Self-transfer, checked bags | High | 4 h | You |
| Airport change | Very high | 6 h | You |
| City visit | Very high | 8 h | You |
Questions people ask
Layovers: what is the short answer?
On one ticket, 90 minutes is enough for a same-terminal connection. On separate tickets, allow three hours, four if you must collect and re-check bags. Add more for a terminal change, an airport change or a trip into the city.
Who does it apply to?
Anyone changing planes. The buffer depends on your ticket type, your passport and visa position, and whether your bags are through-checked. Self-transfer travellers and visa-nationals transiting countries that require a transit visa need the longest buffers.
How much does it cost and how long does it take?
The layover is free; the extras are not. A lounge pass is roughly USD 30 to 60, a transit hotel room USD 60 to 150, a train into town USD 5 to 15 each way, and a taxi USD 30 to 70 each way (2026 estimates). A missed self-transfer flight costs a full new fare.
Can I leave the airport on a long layover?
Only if you have at least six hours and the right to enter the country. You need about two hours back at the airport before departure plus the round trip to the city. Check the visa rule first, because leaving the transit area can require a visa.
What happens if I miss my connection?
On a single ticket the airline rebooks you on the next available flight, and may provide a hotel for an overnight delay. On separate tickets the second flight is simply lost and you pay for a replacement. Travel insurance may cover some of it, depending on the policy.
Do I need a transit visa?
It depends on your passport and the country. Some require a transit visa for certain nationalities even if you stay airside; others let most travellers transit visa-free. Check the destination's immigration authority before booking.
Are overnight layovers worth it?
If the connection is the next morning, book an airport hotel. Some airlines provide one on a single ticket, most do not, and low-cost carriers rarely do. Confirm the terminal is open overnight before planning to sleep in it.
