Last night a friend emailed me a question. He recently flew through ATL, and noticed *some* (not all) arriving aircraft were met "at the end of the runway" and towed into their bays. He didn't notice which bays in particular -- but he did mention that it was different airlines and different plane types.
He was wondering why this would be the case. My guesses were (unlikely) fuel-saving measures or (more likely) jetwash restrictions (I remember we had to be towed into one of the gates at LGA for this reason).
Why would aircraft be towed to bays from the runway/taxiway at ATL?
