I love that you dont pay for your 2 pieces of luggage. If you cancel you dont really lose your $$ instead you can reuse it. The flight attendants are usually funny. I was traveling with my service dog and sat in the last row on a full flight. The attendant kept others from sitting in the middle seat so I could have some room with my dog. It was a full flight so it didn't happen, but I thought it was a really nice gesture.
