The big difference is freedom of choice. Want an early command on an unpopular fleet or prefer to wait in the right seat on a LH fleet? In BA & QF you can do this. In CX there’s no such thing as choice. Join on the 747 & fly a freighter roster for the rest of your life. And bases are over so it’s HK for your whole career now. HK’s good fun but for a few years but a lifetime in a shoebox breathing noxious fumes just doesn’t compare to life and a job in the real world.
