Flight times and durations
Two quick questions, if I may:
1) Why would an airline allot different flight durations for an outbound and return flight? Route in question is STN-BDS. 07:55-11:45 (2 hours 50) outbound and 12:10-14:15 (3 hours 5) inbound? The scheduling department cannot know the exact flight's duration in advance and I know there is always a 'buffer', but why the extra fifteen minutes on the return flight?
2) Is there a website that gives accurate, actual flight durations? I know FR don't put details on FlightStats, but are there any others?
