Frankfurt is hardly a 3rd world checkin location. I got the b...h to call her supervisor or supposedly she did and still she would not check me through even though I showed her 3 CX boarding passes correctly issued in the other direction for AY flights. Then , have you tried contacting AY customer service ? well you have to call Finland and they tell you a charge will apply for their time to talk to you. Nice little earner given the amount of complaints they must get.
