I'll take a stab. He may like the 2 hour bus rides to downtown Seoul. Or perhaps the homeless/crime issues of Capetown? The marathon walk to the bus in Santiago? Runway changes for HND? Bouncing along the ITCZ for 1/2 the JNB flight? Political instability in Lima? OIS instability. Payload Optimization? System resets? Late operations? The Starship isn't quite the magic machine it was portrayed to be, but it is ok. The issues mentioned can be similarly found on other DAL operations. If I had known what I know now (including the same payrate) I would have gone to the A330 for a better choice of destination and no/little FRMS issues. But 330/350 beats domestic for schedule and not getting beat up by reroute.
