What the journey looks like
Direct or connecting, how far the route really runs, and what happens when a connection is missed.
- Direct or connecting
- 0% of the services we sell on this corridor run through without a change. The remaining 100% involve one connection.
- How far it really runs
- The route covers 14,876 km against 14,155 km in a straight line, a detour of 5 percent. Track and road geometry account for the difference.
- Where the change is
- Connections are made at Beijing. The gap between arriving and leaving is 57 minutes, of which about 5 is walking.
- If the connection is missed
- The tightest connection we sell here has a 17 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.
Bangkok is large, and the road in from BKK can take longer than the last hour of the flight. Cars are not our business.
A car waiting when you land in Bangkok
