Mrs pyffii and I are travelling from Melbourne to Corfu in May on a DONE4...We are via HKG and LHR on BA and then Aegean Air from Athens to Corfu ( 5 hour stop over )..It would appear thT Qantas/BA and Aegean have an interline agreement so luggage should be checked through to Corfu...My question is can we access the BA Terraces lounge for a few hours before proceeding through Immigration...Thanks in advance for any help
