We used to have posts about the AIrline industry when it was one of the prescribed sectors – I set up the Forum Thread ‘Using an AIRLINE for T8’ back in 2015.
If you paste this thread title into the search facility it should bring it up for you. However please bear in mind that the airline sector has been through a lot of radical changes since 2015 so not all of the information on that thread may still be relevant in 2022.
