I am an ex aircraft technician. This will explain my habbits.
I still check under the seat for my life jacket. Twice I have found it missing, shame on the person who stole it
and it has held up the departure of the aircraft. Once with North West and the other time with United. The Cabin crew on both occasions did not believe me and checked and then a new one had to be bought in by one of the maintenance staff.
So if you were on any of those two flights, sorry.
