Travelled IB in Business as Oneworld Emerald 3 weeks ago LIS-MAD and was given an invitation to access the AF lounge (think it is the above mentioned Blue lounge) Perfectly adequate for a 1 hour stay with sandwiches/pastries/beverages/a couple of computers and free wi-fi. Not to mention a very attentive lounge receptionist who came around to personally notify me of a flight delay and the subsequent boarding call - I think she was a bit bemused by an Australian speaking Portuguese with a Carioca accent and felt I merited all the help I could get.
