How long do you really need? What can you do with 4 hours at Changi? Is a CDG connection in 75 minutes safe? Find out below.
< 1 hour
Very tight
Do not attempt unless connecting within the same terminal on the same airline. Any delay = missed connection.
1-2 hours
Minimum safe
OK for same terminal, same airline, no checked bags. Still cuts it close at busy airports like LHR or JFK.
2-4 hours
Comfortable
Time to get through immigration, grab food, rest, and board comfortably. Book lounges if you have access.
4-8 hours
Explore time
City visit territory for well-connected airports (SIN, AMS, FRA). Time for a lounge shower and proper meal.
8+ hours
Day layover
Consider transit hotel if overnight. Full city excursion possible at most hubs. Some airlines offer free hotel.
Multiple (1-4 + Jewel)
MRT into city takes 30 min, costs S$1.80. Requires a Singapore visa if your nationality needs one — check before exiting.
Watch out
None to speak of — it's the world's best airport for a reason.
Best for
4+ hour layovers — use the time to explore Jewel Changi at minimum
#1 airport in the world (Skytrax 2023-2024)
Single terminal (D, E, F piers for Schengen)
Direct train to Amsterdam Centraal every 10 min, 17 minutes, €5.60. City is totally walkable from Central Station. Perfect for a 3-4 hour layover.
Watch out
Can get very crowded in peak summer (June-August). Security queues can be 30-40 min.
Best for
3-5 hour layovers — pop into the city for stroopwafels and canals
Consistently top 5 European airports
T1, T2, T3 (Emirates uses T3)
Metro Red Line runs from airport to city (30-45 min). Burj Khalifa and downtown accessible in a 4-5 hour layover. Hot in summer (June-September, 40°C+).
Watch out
T1, T2, and T3 are separate buildings — connections between them require significant time.
Best for
Long layovers 6+ hours — excellent for a Dubai city taste or using the airline lounge
World's busiest international airport
T1, T2 (domestic), T3 (international)
Tokyo Monorail to Hamamatsucho: 15 minutes, ¥490. Then JR or Metro to any central Tokyo station. Even a 4-hour layover allows a quick central Tokyo visit.
Watch out
Immigration can be slow during peak travel seasons. Limited English signage in some areas.
Best for
Any duration — the airport itself is worth exploring, city access is excellent
Consistently voted cleanest airport in the world
T2, T3, T4, T5 (separate terminals)
Elizabeth Line to Paddington: 24 minutes, £13. Paddington to city center: 10 min. Realistic city visit requires 5+ hour layover — add more buffer in peak season.
Watch out
Famous for delays and queues. Border control queues can be 45-90 minutes for non-EU/UK passports. Extremely expensive food. T4 is a separate building requiring a bus connection.
Best for
6+ hours for a London day trip. For short layovers, stay airside and grab a proper meal.
Busiest airport in Europe
T1, T2 (A,B,C,D,E,F,G), T3
RER B train to Paris city center: 35-45 minutes, €11.80. Gare du Nord is a central hub. Realistic Paris visit requires 6+ hour layover due to train time and crowds.
Watch out
CDG is notoriously confusing — terminals are spread over a large area with sometimes unclear signage. T1 is chaotic. Connections between terminals require buses or inter-terminal trains.
Best for
Long layovers (6+ hours) for Paris. Otherwise, stay in the terminal — connections are complex.
Second busiest in Europe
T1 (A-C, D piers), T2 (E, F piers)
S-Bahn S8/S9 to Frankfurt city center: 12 minutes, €5.75. Very easy to pop into Frankfurt for Römer square and apple wine in a 3-4 hour layover.
Watch out
T2 requires an inter-terminal bus that can add significant transit time. Lufthansa strikes occur occasionally.
Best for
3+ hour layovers — excellent for a quick Frankfurt city stop
Hub for Lufthansa, third busiest in Europe
Single (A-E concourses)
Free transit visas for many nationalities. Doha city 30 min by taxi/metro. Free layover city tours offered by Qatar Airways for long stopovers.
Watch out
Doha city is expensive and best in winter (Oct-Apr). Summer is brutal (45°C). Metro limited coverage.
Best for
Any duration — the airport is genuinely world-class. Long layover city tours are worthwhile.
World's Best Airport (Skytrax 2022, 2023)
Single main terminal + satellites
Airport Rail Link to Phaya Thai: 28 minutes, ฿45. Then BTS Skytrain or MRT. Bangkok requires minimum 5 hours to make a city visit worthwhile given traffic.
Watch out
Bangkok traffic is notorious — factor 60+ minutes each way during peak hours. Airport itself can be crowded.
Best for
Long layovers (6+ hours) for Bangkok. Short layovers: get a Thai massage and some real food.
Major ASEAN hub
T1-T8 (spread out, separate terminals)
AirTrain to Jamaica, then LIRR or E/J/Z subway into Manhattan: 50-70 minutes, $8.75-$15. Realistic NYC visit requires a 5+ hour layover. Traffic can add significantly.
Watch out
JFK is notoriously chaotic, underfunded, and confusing compared to European/Asian peers. Switching terminals often requires going through security again. Delays are common.
Best for
Long layovers — go see NYC if you have 5+ hours. Otherwise hunker down in a lounge.
Major US gateway; notoriously inefficient
T1 (International), T2/T3 (Domestic)
Train to City Circle: 13 minutes, $21.80. Sydney CBD is compact and walkable. Even a 3-hour layover allows a quick city circuit.
Watch out
Train is expensive (one of the world's most expensive airport rail connections). AQIS (biosecurity) can be strict for food items — declare everything.
Best for
3+ hour layovers — easily one of the most accessible airports for city dipping
Main Australian gateway
T1, T2, T3
Narita is far from central Tokyo (60-90 min by Narita Express, ¥3,070). Only worthwhile for 7+ hour layovers. Consider staying at a capsule hotel in the airport area instead.
Watch out
Long transfer to Tokyo city. T3 is a separate low-cost terminal far from T1/T2.
Best for
Short layovers: enjoy the airport itself. Long layovers: onsens and city. Very long: overnight Tokyo
Tokyo's main international gateway
Every airport on this page is city-accessible. If your connection is long enough to leave, these are the three things that decide whether it is worth the trip out.
Drop your bags first
Left-luggage near the station or in town, so you are not sightseeing with a carry-on.
Book the ride in advance
A fixed-price transfer beats hunting for a taxi when the clock is the whole problem.
Self-guided, on your clock
An audio walking tour you start and stop yourself — no fixed meeting time to miss.
Affiliate links — we may earn a commission at no extra cost to you.
Download offline maps and your next boarding pass before landing.
If layover is 6+ hours overnight, research transit hotels — often cheaper than missing a day of your trip exhausted.
Duty-free shopping is genuinely cheaper at airport for spirits, perfume, and chocolate — but compare prices on your phone first.
Airport food has dramatically improved. Skip the obvious chains and look for local restaurant brands in the terminal.
Never rely on the MCT (Minimum Connection Time). Airlines guarantee the aircraft but not your bags. Add 30+ minutes of buffer to the minimum.
Carry a universal power adapter, lip balm (aircraft air is extremely dry), and a neck pillow for any layover over 2 hours.
