777
Pros- Great network, lots of movement on/off fleet so likely to move up the seniority list more quickly. Lots of DEP likely to join this fleet so seniority will improve rapidly
Neg- Lots of two crew, east coast, low credit trips so expect to work 5-6 trips per month and most weekends
787
Pros- Great network. Large fleet and will see the biggest expansion in future years. It is also rumoured to be dual fleeted with 777-10. Lots of movement and lots of DEPs expected so similar to above.
Neg- Expect to work most weekends as a junior pilot. Very efficient fleet so expect high hours.
350
Pros- New aircraft. Small fleet of 18 aircraft so expect to fly with same crew more regularly.
Good network, if somewhat limited. Seems to be the most likely fleet to enjoy weekends off as a junior pilot.
Neg- No future deliveries, and no orders. Most pilots relatively new to the fleet, which means there is unlikely to be much, if any movement in the next few years. Relative seniority will stay the same once all recruitment to the fleet is complete in the next few months. Expect to be junior for a long time and work more two crew, low credit trips.
380- Pros- Again a small fleet of 12 aircraft so you will become familiar with crew and destinations. High credit trips.
Most inefficient fleet so expect more time off.
Neg- No future orders, and likely to be the first fleet to downsize in future years. Very few destinations so little variety. Few weekends off as this seems to be the currency of choice.
