It concerns a two way trip Athens-Rome and Bologna-Athens. Although we had bought our seats in advance and paιd for our (20kg) suitcases (by the way, due to a "site problem" our request to pay for our suitcases along with our ticket, was not "recorded" and so we payed 40€ instead of 25€) they informed us at the airport that we were obliged to do an on-line check-in in advance. We had been bombed with dozens of spam e-mails selling cars and hotel rooms as a part of their strategy of confusing the customer. They finally said that this "small" detail was mentioned in "small print" when we bought our tickets. That cost us 55€ pp (total 165€). On our way back from Bologna airport the poor speaking English ground attendant was trying to make us pay 25€ pp because, although we had already checked-in online, she said that we should have printed our boarding cards in advance!!! Only when we told her that we had no money and we had absolutely no intention to pay (by the way, in most airports there are machines where you can check-in and print your boarding pass, but not there) was she kind enough to inform us that we could download an app and get a digital boarding pass instead! The seats were very narrow at our flight from Bologna to Athens (they were OK at our flight from Athens to Rome). At Bologna airport, we had to wait standing for at least 1 hour until our final boarding. Nowhere to sit. Endless lines! Conclusion: Cheap tricks for expensive tickets! NEVER AGAIN!
