A strange situation at CAI.

According to BA's website CAI has a third party lounge - based on my own extensive use of CAI this, I am 100% sure, is a correct statement.

However I've just printed an itinerary for me to fly BA CAI-LHR-CAI next week and it states the following in respect of CAI lounge access:

Admirals Club Lounge - American Airlines Concourse, after Security, across from Gate 12.

As far as I'm aware AA doesn't even serve CAI, so what they are doing with a lounge here is beyond my comprehension. I will check out the situation next week and revert.
