Hi pibbem, a pity you’ve not enjoyed flying with QF. I’ve had the opposite experience and have no problems flying with QF. I don’t mind others, find the service fine, but look for QF first. Usually the seat comfort is the biggest thing for me. I don’t rate the entertainment so much, I use my iPad-mini more often

For US airline crews, I’ve actually found them not much different from each any other airline. Have only flown delta and AA.
If you give the crew cough they’ll get assertive with you. If you try to work with them you may get through ok. I find the policies much worse than the staff. I always try to give myself 4-5 hrs for intl connections (if possible for me) because of their massive
overbooking practices. The extra times are annoying BUT i can work in the clubs and it allows me at least 1 flight being missed but still able to make my connection. 2 mths ago out of charlotte I got the last seat on a flight AFTER being in the standby line because their system had pblms with my online checkin. But the auto-check in’s ask “would you accept a ‘bump’ compensation?”, with nbrs up to us$500. I think ppl actually work with it to book early flights, tick for an amount, then hope to get bumped+paid, fly later and effectively have their trip paid for!
Frustrating sometimes, I was a little nervous but not too much about getting my connection, but you do have to work hard at not holding staff accountable for their employer policies. I just try to set myself up to minimise the impact.
On Friday morning I went to Cbr airport 4 hrs early because winds were coming. Asked QF if I can get to Sydney earlier to increase my chances of connecting. They’ve done this for me 4 times in the past, even on econ-sale tix. I just accept my role in doing everything I can to make my trips work. Setting up to work a few hrs in the airport is part of that.
Cheers
