Arriving at LHR the other day, I was somewhat surprised to see that T1 and T2 share an arrivals corridor for a short distance (we arrived at gate 139). All along the length were signs indicating that you should know which terminal to arrive at - presumably so you go into the correct arrivals hall for your baggage! The corridor eventually split, one way to T1, the other to T2.
This seems potentially confusing to me. There was no mention on the aircraft of this, that we should follow the signs to T1 (which *I* knew, but maybe some didn't...?). Anybody else got concerns about this?
I guess BKK has a similar kind of problem, since both terminals are actually one terminal airside. Any others like this?
