One for the guys near LHR.
From the 25/10/09, Air France will have 2 extra flights per day to Paris CDG. Both flights will be operated by Airlinair ATR42-500 aircraft. Schedule as follows:
LHR d.08.20 arr CDG 10.50 (AF2081)
LHR d.17.10 arr CDG 19.35 (AF1581)
CDG d.14.40 arr LHR 15.05 (AF1580)
CDG d.20.50 arr LHR 21.15 (AF2080)
Going by that schedule it looks like the flight arriving LHR at 21.15 night stops to do the 08.20 departure the following morning.
Cheers,
Ian
