Yes. I travel frequently to the US, and have used many airlines. Several years ago I did fly American Airlines. Can't say I was too impressed with their service though. I think one of the best airlines is Air Canada, for their friendliness and efficiency. One of the worst was Qantas, mainly because of the rudeness of their staff.
Gee, norma, you seem to have a big problem with QANTAS!
In all my years' having to fly, I NEVER once encountered 'rude staff' on QANTAS,
Quite the opposite actually!
I firmly believe that any 'service industry' person's response, depends on how they're spoken to...........they're not employed to take 'rudeness' from ANY customer, & neither should they!
Times' have changed, thank goodness!
