The layover makes or breaks a one-stop itinerary. Here is how to judge one before you book.
The safe minimum
For international-to-international connections on a single ticket, treat 90 minutes as the practical floor. Airlines will sell 60–75 minute connections that are technically legal, but one late inbound aircraft and you are being rebooked — possibly a day later on peak dates.
If the connection involves changing terminals, or you are on two separate tickets (self-transfer), the floor rises sharply: 3 hours minimum, and on separate tickets the risk is entirely yours.
The comfortable ideal
2 to 3.5 hours. Enough to absorb a moderate delay, clear transit security, walk to the far gate, and board without running. In big hubs like Singapore Changi, Kuala Lumpur or Doha this window feels relaxed rather than wasted.
When a layover is too long
Beyond about 6 hours, a layover starts costing you: a meal or two, exhaustion, sometimes an airside hotel. Overnight layovers deserve special caution — a 02:00–08:00 wait is far more draining than the same six hours in daytime, especially with children.
Hub notes
- Singapore (SIN): fast transfers, excellent facilities; 2 hours is comfortable.
- Kuala Lumpur (KUL): allow a little more if transferring between terminals.
- Doha (DOH) / Dubai (DXB): big airports, long walks; 2.5 hours is a sensible minimum.
- Colombo (CMB): compact; short connections are usually fine.
