All things being equal, how long in a normal company (ie no low-cost, they have no long haul yet), , can you expect to move right to left on long haul ?
8 to 11 years ? Considering people coming in at 1500 hours instead of 300 for scheduled airlines, you save 2 to 3 years, as a consequence 5 to 8 years meaning at 1500 + 8*500 = 5500 hours you can find a left hand seat in a 7X.
Good luck anywhere else.
For the ex long haul, bus drivers; if only size matters, drive eastbound, etihad, Emirates or else, with all your incredible, unvaluable experience, you should have a Left hand Seat right away....
Bottom line, you decide to go GA charter with an airline like lifestyle,you pass the selections, you enjoy as many days off as you can while commuting at company expenses...And you learn the sops and part A please...
