But they only do one tour in the air, the rest of their service is / or can be ground based, the first tour is obviously simply a sweetener to get them into what is a mundane job
After your first flying tour, unless you transfer to 32 (TR) Sqn, you will be employed on the ground, for at least one tour; supporting unit food services with our industry partners or as a member of 3 Mobile Catering Sqn, at RAF Wittering, providing military field catering on Operations and Exercises worldwide. Returning to Cabin Crew duties, after a ground tour, will be voluntary or to meet the need of the Service.
Even the trade description makes it clear they are not totally air orientated.
