If you read threads/posts elsewhere reagrding the crewing/roster problems, it would seems an odds on certainty that to increase a/c utilisation will cause total chaos. Any hicc-up would devastate the network. That would cost a fortune to the company and irritate the crews more than they seem to be. It would a no-brainer.
At a time when ej seem to be undercrewed, and with a/c due to arrive at an ever increasing rate, probably faster tha they can train up to the correct crew ratio, surely the opposite is required, i.e. reduce the schedules to match the assetts available.
Or could it be short term greed, again, ruling the day?
If by going charter they can block book X% of seats at a guaranteed price to a tour operator, but on exisiting flights, that would be a guaranteed source of revenue. How the legal/licencing matter would be sorted out might task the powers that be!
But I would have thought that first they should be sorting out the fundamentals to make ej more attractive to crews for a carreer, not less.
