Pros: We arrived.
Cons: Boarding is a free for all mess. No benefits are given to Star Alliance Gold members. Even though by the rules gold members are supposed to be allowed in the lounge I was very rudely refused entry. The reason given was that it was not an Argesn flight (???) Really? I booked on Aegean, Aegean charged my credit card, the plane said "Aegean" on it, the pilot identified it as an Aegean flight. With a seven hour layover on an international United/Aegean itinerary this was a major inconvenience. The airport staff is very cold and unhelpful but the plane crew was nice. In the future I will fly one of the budget airlines and save some money. The service could not possibly be worse and at least I won't be expecting to be treated as a valued customer.
