I was in the back of a guppy last week into SEA. OAT around 55. Pulled into gate and no air, no APU. Just recirc fan comin out that eyeball.

It got very warm very quick but it was the lack of any air that was the worst. Extremely stuffy with many bodies crammed in a 100 sq ft area. Stupid uncomfortable.

Of course the crew was gone by the time i passed the flight deck but the word NEEDS to get out to these guys to wise up and provide for the pax.
