hats off to you and your wifeTook a upgrade to Boston. Boarding we got several dirty looks when we bought 3 seats. Me, my wife, our 2 year old and a 6 month old. When we landed everyone was saying how good our kids were. They flew well. My responce was " Thank you but I enjoyed the look on your faces when we boarded"
Lots of good info here, x2 on eating drinking and napping. It will be fine, you paid for a ticket too.
