Ok have some questions and maybe more later. I am traveling with 3 children ages 6, 4, and 2. 1. Saw posted on another board that people with children like sitting behind the bulkhead for more leg room. What is the bulkhead? Would you suggest me to sit there? 2. What is curbside? 3. can someone do my airline shopping for me? Just kidding! Even though i have no clue how to get the best rate I just keep checking every day. Thanks!
