ALso have heard that a new computer sys is in the works but I don't think GF would ever go to a strict seniority bid which can be ineffecient depending on how it is implemented. EK rotating block system works much better with everyone getting a crack at some good flying.
I also agree with Ironbutt - the biggest issue is airplanes going down and the shift in flying it takes to cover the flights. The lack of crews doesn't help........and it goes on. Crew sked is left to pick up the peices and fix the problem.
