It does not list them all, it would be too much to expect an alliance with thousands of aircraft flying all round the world to be able to work out where a few hundred fixed lounges were in destination airports. This sort of database programming would defeat even the most advanced two year old. Having failed in this task, you will be reassured to know that the team were sent to Heathrow to sort out the baggage transfer issues.
Look at the disclaimers, just because it is listed does not mean you will get access and we cannot be bothered to tell you which ones are which for third party lounges. Hell, even if you are on a codeshare we might tell you to get lost.
