Good luck with your travels! You should have no problem as long as you truly are FLEXIBLE. I took my first hop back in October with my 5 month old. We had a great time... um... for the most part.
Some helpful tips...
Please bring layerd clothing. I was so hot before the plane took of and absolutely frozen once the plane got up to altitude. I was on a 135 though so that was part of the deal... I actually used a baby wipe to clean off my daughter at one point and set it on the floor when I was done. IT FROZE TO THE FLOOR!! Yeah... please bring warm clothing, blankets, sleeping bags... etc. There's nothing worse than being miserable for such a long period of time.
Hearing protection. They were nice and offered ear plugs but like an earlier person mentioned... the foam type DO NOT work for children. I even tried trimming them down for a more custom fit but they kept popping out. It's SO incredibly loud up there I worried about how it was affecting my daughter. The wax ones, on the other hand, are awesome. I used these on my hop back. You might even make friends if you have enough to share. ;)
MONEY MONEY MONEY.... you probably will need more money than you plan for. You might need to pay for hotel... food... etc for any number of days if you get bumped. We experienced mechanical delays and were almost bumped several times.
Entertainment... for the flight and the wait... you never know how long the wait will be!! Time sure seems to stand still when there is nothing to do. Books, magazines, toys etc will all come in handy.
Oh... and my little tip... I called the PAX terminal almost daily for months before I planned on going home. (The one here at Mildenhall has a recording you listen to.) They would only give a listing a few days out, but I was just checking too see how often flights went near my home. I just jotted down on my calendar so I could make more of educated decision about which time of the month was best to catch a flight.
Good Luck!!
