Since the staff and flight crews park in the Humphrey terminal ... I find watching the FAs is quite an enjoyable pastime when taking the train.

Yes the walk is long (I did part of it before the garage was completed). Then you have the walk from the train to the next train then to the terminal!

All in all .. everyone who parks at Humphrey or flies out of there (connecting to Lindberg) gets their walking in.

But supposedly for those who only go to Humphrey the parking is very very convenient. Tho the larger garages are designed for overflow from the other terminal (until Lindberg gets more parking).
