On our flight to Orlando from New Orleans last week I had A29 while the rest of my family had B1-B-4. I opted to wait and board with them. Huge mistake! Not only did SW do Family Boarding, they let entire families (including grandparents) board. I could not believe what I was witnessing. By the time we were allowed to board we had to get to the last two rows in order to sit with each other. It was my youngest child's first time flying and was surprised that with B1 boarding we would possibly have to sit apart.
