Jet 11,
Flts are not cx due to a lack of flt crew because we are efficient AND flexible. I know the former because I have flown for both mil and other civ companies and can compare.
In terms of flexibility you should watch aircrew running from one a/c to another on LHR T/Rs in order to make schedule.
If we, as an entity, displayed the same amount of inefficiency and apathy as some (note: some!) elements of the Company, you will, indeed, see flts cx due flt crew!
