OP, this is my fear too. Did you buy Early Birds and still get B boarding passes? How far out did you buy the Early Birds if you did? We are traveling with our 3 granddaughers in early August. I bought the tickets and the early birds 6 months before the flight. I'm hoping that will help us stay together in boarding. One of my granddaughters has never flown before and they are 8, 10, 10. While they are older, this is the first time we are traveling with them alone (out numbered). I'm hoping to be with the 8 yr old and the 10 yrs old that has never flown. My husband and the other granddaughter can hopefully be together somewhere else. I'm having buyers remorse now.
