The airport you connect through is not a neutral choice. Two itineraries with the same journey time and similar fares can have very different risk profiles depending on where the connection is.
Some airports are efficient, compact, and reliably on time. Others are sprawling, prone to delays, and have connection logistics — terminal transfers, immigration queues, gate distances — that require generous buffer time. Knowing which is which matters when you're designing a multi-stop international itinerary.
The airports that consistently work well for connections
Singapore Changi is widely regarded as the gold standard. It's fast to transit, well-organised, has good facilities for layovers, and has historically excellent on-time performance. For connections to and from Southeast Asia, it's hard to beat.
Hamad International in Doha (Qatar Airways' hub) is similarly efficient. Well-designed, compact enough to transit quickly, and Qatar's operation tends to run well. For connections from Europe to Asia or Australia via the Gulf, it's a strong option.
Zurich Kloten and Amsterdam Schiphol are both well-run European hubs — compact compared to London or Paris, reliable, and with good connections east and west.
Tokyo Narita and Haneda are exemplary for Japan connections. Everything is organised, signage is clear, and delays are genuinely uncommon.
The airports that add risk
London Heathrow is one of the world's busiest airports and its terminal structure creates genuine connection risk. Terminal 3 and Terminal 5 require a bus transfer or underground journey between them, which takes time that many connections don't allow for. Add any delay on the inbound flight and comfortable connections become tight ones very quickly.
JFK is notoriously inconsistent. The multi-terminal structure, variable ground transport between them, and the airport's reputation for delays make it a less desirable connection point than Newark for transatlantic connections, even though it's the same metro area.
Paris CDG and Frankfurt can both be unpredictable during peak periods. CDG in particular has a complicated layout across multiple terminals with different levels of connection efficiency.
Matching the connection airport to your itinerary's risk tolerance
The question to ask for any connection isn't just 'is the time sufficient?' but 'is this airport one where that time is actually comfortable?'
A 90-minute connection at Singapore Changi is fine. A 90-minute connection at Heathrow between different terminals, especially on a route with any history of delay, is stressful. The same amount of time, very different experiences and risk profiles.
Occasionally, routing slightly out of the way through a better-organised hub — adding 45 minutes of journey time to connect through Zurich instead of a more direct connection through a difficult airport — is the right trade-off. If you'd like help thinking through the connection logic for a specific itinerary, that's exactly the kind of problem a flight specialist is useful for.
