Different life stages Turning Finals. Young and single and wanting to see Australia? 737 is the go. Been there done that with a new family? You might find the dream just becomes a job.
330 people I know find it a lot less fatiguing. Bigger cockpit, quieter and less stressful than Ballina on a weekend using see and avoid. You don't have to worry anyway unless you a 3 years old when you join you won't see a widebody slot at Virgin. Widebody work is the realm of large overseas airlines with different cost bases. All the best.
