hi, i commute this flight quite often i checked the last two flights i commuted in on and the off times were accurate but the on times were off by about 10 early in both of the flights. i specifically checked the flight time on arrival. the flights were nwa 1810 on 11/30 dtw-cle and commutair 8825 on 12/1 cle-dtw.
we landed about 6:01 pm on flight 1810 which provides wheels up to wheels down time of about 31 minutes. your system shows 24. and then tonight commuting home we went wheels up at about 4:10 and landed just about 32 or so minutes later. i dont know why the inconsistency? but i was there and it definitely exists.
