The inflexability does seem economically stupid - lets not forget the winter peaks in Christmas & the new Year. BMI might use their ERJ's - and how about those Flybe ex Bacon ER's that are comming to the end of their lease's - Is it possible to statisticly predict demand during the lighter demand Mid day / afternoon periods and operate a pool system for A/C - The competition is best fundamentalists would not like it - tough ! - Peops get their freq of service and less fuel is burned.
Life in the ERJ's yet ? perhaps - I know about crewing validation probs as an igorant SLF,but some idea's please.
