What the journey actually looks like
Direct or connecting, how far the route really runs, and what happens when a connection is missed.
- Direct or connecting
- 75% of the services we sell on this corridor run through without a change. The remaining 25% involve one connection.
- How far it really runs
- The route covers 2,453 km against 2,381 km in a straight line, a detour of 3 percent. Track and road geometry account for the difference.
- Where the change is
- Connections are made at Bengaluru, Chennai, Hyderabad, Ambalantota. The gap between arriving and leaving is 53 minutes, of which about 5 is walking.
- If the connection is missed
- The tightest connection we sell here has a 18 percent chance of not being made on the timetable alone. Part of this journey is a self transfer between separate tickets, so leave more time than the minimum and expect to check in again.
- First and last departure
- The first service of the day leaves Bangkok at 06:29 and the last at 18:42, across 16 departures. The return direction keeps its own timetable, so the times back are not these times reversed.

Where these numbers come from
Observed service A carrier record shows this named operator serving this named pair, and we carry that through unchanged.
Schedules, seat counts and fares are generated by our own model until the supplier contracts are signed. Places, coordinates, operators, which operator serves which pair, and every distance are real. We would rather say that on every page than let a modelled number pass for a filed one.

CMB is not in Colombo, and the road in from it is the part of the trip nobody plans. We sell the flight and stop at the terminal door.

Settled in advance, so the ride into Colombo costs what it said it would rather than what the rank says.
