he reckons you have to spend about a third to a half of your flying pay when 'down route' on meals and general living costs, and that's without going mad.
Seconded.
As a Long Hauler I'd say I probably spend most of the duty pay ("allowances" in old terminology) on most trips - which of course is what it's designed for and is certainly where the taxman thinks it is spent..
. That leaves you with your flying hour pay to spend or save as you see fit. All in all I'd say the proportions you're working on are fairly reasonable,
however the spend/save proportion
may be different in short haul - anyone care to comment?
