I’ve flown the 380 many times (BA, EY and QR)all in Biz class.
BA from LHR to HKG
EY from LHR to AUH and back
QR from DOH to LHR
QR was the nicest flight I have ever taken, flight, staff, food, comfort, AV.
I have also flown 787 from IAD-AUH-IAD, very nice and quiet plane.
Flew Cathay’s A350 from HKG to BKK. Super quiet ride, and top-notch Cathay food and service.
My only 380 experiences have been on EK between JFK <=>DXB <=> HKG.
There are several airlines that are operating both the 787 and the 350 out of Boston so I suspect that I'll be flying them eventually.Lufthansa is also flying the new 747 out of Boston and I must admit I'm curious about it as well.
As for Cathay Pacific...we found on our only flight with them that their service was excellent...even in coach...even on a 15:55 flight (16 hours and 8 time zones!).
CUS and HEO, but of course, ZOI, and JWM but only when you ESAD
