I hesitate to complain, because I did get the last two award tickets available on Concorde at the time I booked (this with no status on Qantas, where I pulled the miles, nor British, on which I flew), but in general award availability is sometimes a problem, even for top status members.

Failure of agents, especially at hotels, to understand the benefits of top status, can be frustrating. I am a good sweet talker, but I shouldn't have to do that. All airline agents seem to know when they are talking to a top status person and how to respond when so doing.

Failure to provide elite security by-pass lines at all airports.

Failure to provide exclusive top status check-in lines at both hotels and some airports.

That's all that bugs me. Can't think of 10.
