I find that at their worst - which is very infrequent - BA CC are very good. They put to shame Lufthansa, American, United, S/H Air France and DEFINITELY US Air and America West.
Baboo are surprisingly good for a small airline that say that eren't an LCC but they are cheap as far as fares go, but not service.
Qantas are nearly as good as BA, but admittedly, I've only had 36 flights on BA so far this year and 2 on American Eagle - they weren't too bad. I'm flying again next week to CPH, so I could report again next weekend if the thread is still running.
