Depends what you want - it’s a worldwide fleet. That’s one of the things that makes it a great fleet to be on as if say you hate the Far East, there’s plenty of US stuff to get your teeth into.
As as a general rule, the senior trips are the SIN, PUJ, EZE, CPT, MLE, MRU of this world. The upper half also hoover up the majority of the high credit 3 day/3 crew work. Plenty of good stuff available towards the bottom though - SAN/LAS are achievable at up to 80% from the top. SIN/SYD more junior than that.
Swapping also allows a huge huge amount of control over your lifestyle. The main thing I struggled with in my first 18 months was nearly continuous weekend work. If you’re about to join/considering an offer on the 777 PM and I’m very happy to send you example so of the bottom 5% rosters. Plenty of DEPs coming onto the 777 so you won’t stay on the bottom for long.
