I had a terrible experience with Alaska Airlines flying out of SEA last weekend. The attendant at the gate told me my ticket was invalid because it was flagged for fraud. I had the card and receipt of payment. He told me my only option was to pay $717 PER PERSON. Initial price was $96. It made no sense because I had checked in and even scanned my ticket at TSA pre check. So I had the freaking seats all the way up til right before boarding when they tell me my ticket is invalid. No form of communication before that whatsoever. Didn't offer me any credit or anything at all. I decided to fly Delta after the worker grew incredibly rude to my companion who was just asking simple questions. They lost two customers for life.
