Well I'm not certain on passenger figures but when I was in Athens airport last week the OA
domestic checkin was mobbed. Not sure about the international routes but certainly the London routes are almost always full. When I flew both the A340 and A300 to and from ATH
and both were full. From what I can remember I don't recall the A300 ever leaving the fleet I think the majority of them were phased out leaving the sole one operating today. Certainly the domestic routes are vital as they are the only airlink to ATH
in the case of certain remote islands and would guess some of them are operated as a public service airlink, although Aegean has certainly given them a run for their money on some routes and will probably get worse as they get their A320s. They were rebranded as Olympic "Airlines" from Airways and believe it's the same old airline but under a different name. There was some talk that a new airline would be formed under private ownership and a new name but I'll believe that when I see it. As for whether it will survive or not only time will tell but I don't think it should be allowed to fold as Greece deserves a flag carrier it can be proud of. Personally the times I flew with Olympic were fine no major faults but I always wished they could be better and I feel for all its employees not knowing what the future holds.
