We're bringing 2 car seats along for our 2 and 3 year olds and will be checking them. Wondering what to put them in? I know they make backpack type carriers for them but I can't easily find them around here (Halifax, Canada) plus I wouldn't want to spend a bunch of money as we might not use them again. We're not interested in using them on the plane plus I'm not sure if they meet the airline safety regulations. Coming home we're direct (MCO-YHZ) but going up we have a stop over in Toronto where we have to get our bags and go through customs. I had thought of trying to fit both in a Hockey bag that I have here but it would exceed the maximum size (62" linear) but not weight. Not sure if the airline (Air Canada) would allow it, certainly don't want to pay the oversize baggage charges ($75 each way I think). They are allowing an extra bag due to the no carry on thing but didn't read anything about allowing extra large bag. This would be nice as the bag has a shoulder strap. My only other thought is to put each car seat in a clear plastic bag. Wouldn't be the greatest for carrying around the airport but it would keep the dirt off them I guess. Anyone do this before ?
