Did a BA798-AY361 LHR-OUL transfer once, I think wheels down at 23:24, with departure at 23:55… I was first off the plane from London, ran as fast as I possibly could from gate 37 to gate 25. I was the last pax on a full A320, doors closed after me and almost immediate pushback. The GA didn't even scan my BP, I was just waved through and told to keep running! I had quite a bit of carryon baggage with me as well, my god I wanted to stop and walk.. But not enough to spend the night at HEL!

Most time efficient transfer I ever did do, but so stressful I'd rather not put myself in that situation again. (Booked separately, under the MCT )
