Was travelling round Europe September last year where most airports have a lounge(s) that accept Diners Club for free access
At two different airports (Catania and Birmingham Intl) was refused entry at the lounges that do accept Diners. After a lot of haggling at Catania, managed to finally get in at the grace of the door b..tch (but at Birmingham, no chop).
On both occasions the lounges weren't full and both had clear signage that Diners was accepted.
Has anyone else experienced anything similar?
