We've flown twice with US Airways to Orlando via Philadelphia. We were quite impressed with the transatlantic flights - individual seat back screens and choice of films etc. Less impressed with the internal flights, though.
We were treated very well by the ground staff in the UK in particular. In April, they asked us to consider being 'bumped' to the following day on our outbound flight. In exchange, we were offered guaranteed business class seats on the following day, overnight accommodation and meals, and $400 each. We accepted. They were so appreciative and treated us like royalty when we checked in (at the special desk with no queue) the next day.
An added (and unexpected) bonus, was that they upgraded us to 'first' on the internal flight on the return journey - without explanation! The transatlantic leg was dire, though. Overcrowded and full of tired, restless and grumpy children! Not much legroom we found, but no experience of other airlines to compare with - except BA Business Class (on company business - I wasn't paying!)
Wish we could afford to travel business or first all the time! I suppose we've been spoiled now - what you've never had, you've never missed! Unlimited champagne and seats which can be adjusted to be almost horizontal are now a distant memory.
