I do not have the information of how many WW planes are available though I am sure it is not 2800 (I really have no idea)
So if it were only 280 WW planes that would be ten years! of an extra flight attendant per flight ?
No extra attendant and it would be just £4.2m a year extra profit
Jack, BA LH aircraft fly every day, often more than 1 flight per day. You cannot just have a single crew for that aircraft - they need some time off! (though don't put ideas into Michael OLeary's head
)
Your numbers quoted above are based upon a single crew for an aircraft. Whereas, I would estimate perhaps 5-6 full crews (or more) are required for each LH aircraft, so you'll need to revise your figures accordingly.
As to your post re the mods, why not post that "vital information" here?
