Don't bother calling the Southwest corporate office, as they are no help. After 3 1/2 hours on hold, I was convinced at the end of the call that I have to change airlines. I arrived at 8:37am for a 8:45 am flight. My name was never called at the airport, and I was not allowed to board. The policy says you should be in gate area within 10 minutes, I was in the gate area not at the gate. Southwest policy says they may not let you board, but Breana said will not and I corrected her about this. I observed 2 other Southwest flights in which paying customers arriving within the 10 minutes were not allowed to board but others were. WHY is a Southwest Employee on vacation such as one on our plane visiting family allowed to take the seat of a PAYING CUSTOMER and board within the 10 minutes? I was told by a pilot that the standby employee must get off the plane for the paying customer. After calling the corporate headquarters and speaking to Breana, she said it was my preference when I said I would start flying Delta after years of flying Southwest. Customers are just a number to them. She did not believe me when I said that my name was not called at the airport. I guess the customer is never right anymore. She also told me a direct flight was full at a later time 2pmish Atlanta to Philadelphia when yesterday a Southwest employee told me it was not. We were put on a connecting flight that was delayed 2 hours in Orlando.
