I got upgraded last year on AMS-ATL and can't recall if it was an Airbus or Boeing but it was a really nice experience. Fully lie flat beds and seat sligthly angled. Trying to choose seats now for next R/T flight in July and will be on both those aircrafts. I'm in 6A and 2A at the moment. Would appreciate any input and also wether bulk head seat is a good option on any of them. Thanks!
