SWhile the new Terminal 2 is spacious clean and well equipped check in-staff are not well trained. I came to the airport and they told me I should have had a hard copy ticket not an electronic ticket and there was nothing they could do about it. I insisted they try and resolve the problem. After waiting until all passengers were checked in I asked again for help. The girl begrudgingly said she'd go to the Main Office and took a French woman passenger with her with a similar problem but told me wait there. They were gone almost an hour and I asked for help from the remaining check in desk woman on duty. She told me she had nothing to do with "my problem" so my husband explained in Arabic and asked her politely for help. She was very rude and very angry I asked her for her name. She started screaming at me "Are you the police? Are you a gendarme? I don't have to tell my name or badge number to anyone but the police." She refused to call her supervisor and continued her contemptuous and rude treatment towards me yelling at me to go sit down. The police showed up and she calmed down. The other woman then arrived with the French woman she'd helped who also had only an electronic ticket but told me the same thing again "We will put you on the plane to Lisbon and when you get there get your baggage and go find US Airways and ask them to straighten it out." The police then escorted me to the plane which was late taking off which had inconvenienced all passengers. And all this problem because they claimed the computer systems don't communicate with Lisbon/US Airways. These employees need better training in customer service or they will run everyone off eventually.
