hi! i live in pennsauken, nj. very close to burlington. i walk romeo @ the waterfront in burlington all the time! small world.
feel free to pm me when you get to the states. we can have a playdate.
good luck flying. maybe check with your vet about giving them something to sleep thru the flight. my vet gives me doggy cough syrup for travel. test out @ home first so you don't have any freaky side effects in the air.
most of us bring a large blanket and sneak our babies on to our lap during the flight. bring wee wee pads and the can tinkle in the bathroom. they should be ok. good luck.
