I know for a fact that "basic salary" is only half the story for Heathrow BA Cabin Crew.
Literally.
The other 50% of their take-home being made up in a disgracefully large amount of allowances.
If this Doris is on £48k basic, you can add about the same again in (tax free) allowances, making her total package....
... a disgrace.
(and before the Mathematical Police get on my case, the £27k pension is worked out on basic, allowances not being pensionable, thanks)
