Yes. But the big focus has been on the widebody portion; namely, what to do for a 767 replacement, and what to do with the A350 order. There's been plenty of reporting on this.
-UA is reviewing their order book and fleet plan; that review is not yet complete
-UA has delayed their initial A350 deliveries
Rumors going around:
-Scott Kirby came to UA; knows what AA paid for their 350s and thinks UA overpaid.
-UA employees saying there's no hype about a new type arriving anytime soon, unlike the 77W...
I wouldn't assume that the A350 order is safe until after they've publicly stated that their fleet plan review is finished.
