I've got my eyes on the A350 for ages now so I'm glad that I landed on the Airbus fleet (80/20 odds in favour of Boeing here at my airline).
I've got two possible progression tracks from here: 1. gain experience on the A320 for a year, get upgraded to the A330, after two years get certified for the A350 to fly A330/A350 mixed. 2. spend years on A320, upgrade to captain, many more years, then finally upgrade to A330 as captain, then two years later A350 added.
I am planning to fly jump seat to see all the types we're flying.
