What you fail to mention is that out of that £1800 , they may well have downroute expenses of approx £300 .
I don't believe that engineers should be paid badly, but having visited a vast BA hangar the other day, no-one there was in a hurry to do anything fast.
The role of cabin crew can be very demanding , and you do get alot of verbal from our lovely customers.
Besides ,if any BA engineer feels they are missing out on something, they are MORE than welcome to apply internally for cabin crew
Believe me , it does happen!
