I flew on LH F in April and it seemed to me to be much the same as the BA experience. CCR and First Terminal only separated by a duck! The car to the aeroplane was nice especially as it parked almost under the wings but the other passengers did not want to stare aimlessly at an engine so I was herded quickly to the lift for the air bridge.
QR F is a waste of whatever you use to pay for it; it is not much better than their J. The bar on the aeroplane is great but it’s for both J and F passengers.
JL streets ahead of NH in every respect. OZ is (was) a five star airline and it remains the worst I’ve flown.
