If you are going to be an FO for that amount of time (probably the same for most IT operators), is First Choice a good place to be for an FO in terms of schedules, destinations, layovers (if there are any actual short-haul layovers), etc? If you are going to be an FO for a long while, it might as well be a nice place to be...
What's the likelihood or odds of starting on the 757 vs. the A320 at First Choice as a newhire? How about odds of 757 vs. A320 as a newhire at the LGW base?
Cheers
