Getting some A350s back into service is very exciting! MEL used to get a daily A380, then switched to daily A350 and it's now 2 777s. I am hoping that these 2 switch to A350s.
It will be interesting to see how this affects the rest of the fleet. Nobody here likes the A330s but they aren't that old (16.4 years on average) so I don't know if QR will be in a rush to get rid of them. Maybe with more 787s being delivered, there is hope. They've wanted to park the A380s; not sure if that idea will be resurrected.
