I have always been told that carseats do NOT count toward your luggage total. They can be in addition to your allowed number of bags. Strollers also do not count toward your carry on allowance. I highly recommend checking your carseat and not having to carry it through the airport. We've done it both ways and this seems to work out best. If your child is big enough, consider a backless booster seat. They're lighter and smaller to deal with. They won't work on the plane, but again they can be checked and will give you less to deal with once you get there!
