Hi, I had a flight yesterday from US NEWARK LIBERTY INTERNATIONAL AIRPORT to Athens Greece. GATEB65 Flight EK210 A33416 AEGEAN AIRLINES (operated by emirates)I tried to get in my account to check in a day before and it didn’t allow me .I did manage to check in on my way to the airport but wouldn’t let me choose my seat. It did it for me. after arriving at the airport and waiting for my boarding pass, I asked the gentleman at the counter if there were any more available seats because I was assigned to a middle seat in the middle row I told him I have severe anxiety attacks because I am claustrophobic, he asked his supervisor if this could be changed and his supervisor informed him that he couldn’t help . as I boarded the plane. I asked one of the hosts if they could help me with my situation they told me to address this matter with a hostess where I was assigned in my area. I did that when I arrived at my seat and I was brushed of .by the time the plane took off. I started feeling a bit shaky and a bit overwhelmed from where I was sitting. I can feel that my panic attack and my anxiety were getting worse. I was trying to be patient as I did not want to cause any problems, but it took the better of me and I had a panic attack. I got up off my seat and was trembling and that is when MS.ABANILLA MA MORENA came to assist me she was amazing, she tryed to make me feel more calm trying to find an aisle seat so I can be more comfortable and at ease.she was kind and attentive to my needs. I am ever so grateful that she helped me so much. Your airline needs more people like her. She was professional and kind I commend her for her compassion and kindness.i would have preferred if it didn’t have to escalate to the degree that it did before something was done about it. It ruined my whole trip.
