graraps - as you seem to think it's inexcusable for BA not to have a spare crew sitting around in every destination they fly to, are you prepared to pay quite considerably increased fares to allow BA to recruit more Captains so this can happen?
I'm not and I'm sure the vast majority of passengers with BA feel the same - just so that 5 flights per year (as my Jumbodriver's post of 5 cases of sickness per year) can be flown out on time.
Please - be realistic.
