AC857 LHR to YYZ. Bottom lumbar portion deflated. I reinflated it myself once then the SD did once. Total reset of my seat a couple of times, eventually the seat control panel stopped working so I had limited functionality in seat positioning for about half the flight. Not sure the SD put the control issue down on the comp form as she wouldn't write that part in front of me. I'm going to follow it up and will post compensation amount when it comes through.

As a note, the SD gently blamed me for the seat control crashing because of too many resets. Not sure if that's actually a thing, felt implausible but maybe someone here knows. She says there should only be a maximum of two resets per flight which seems like an arbitrary number?
