Hi again, I can't seem to put another post up, so I am writing here on the edit feature. :) I just thought of something else.
If you have a double stroller that has it where it is front and back seating versus the side by side, you can get this really neat attachment to the back of it called a baby boogy board that attaches to the back of the stroller. There was a recall but they have now provided free kits to repair and I am sure that there are new ones on the market now that are safe since the recall.

That way you can have the baby and one 2 yr old in the seats and one of the tots riding behind while dad handles the bags.
Good luck! :)
that is the hardest thing about traveling with little ones, the airport. I honestly did not know how I did it with my 2 and my husband by my side. He made everything so much better when we did those things.
The best thing to tell you is to get a huge stroller. Something that can transport all of your kids in the airport. I have not been stroller shopping in ages but maybe there is a stroller built for 3? Check to see too if the toddlers are old enough to sit with a lap belt, I know that helped tons with us and our oldest. If you can't make sure your car seats are approved for the air plane too. That is a must or you will be made to check them in with luggage. From what I was told, but I would just double check and rules could have changed but I was told that kids in car seats had to sit by the window in case of an emergency. That way the seat is not blocking a person from getting out.
If you are flying when terrorist threats are low, I believe you can get curb side check in. That could help you out a whole lot too. That way your husband could just handle transporting the car seats to your terminal while you handle the kids in the stroller.
Good luck
