While we have a Britax Boulevard for the car, we have another for air travel that is lighter and narrower so a lot of the issues about fitting seats are overcome (it is 17 inches wide). The US version is noted on several threads as the Cosco Scenera. That model is not sold in Canada and is not authorized by Transport Canada but probably would be if anybody sold it. Instead, Dorel, which markets the Cosco brand, sells the Scenera under their Safety First brand at Walmart. It is very cheap and easy to use with excellent instructions. It is convertible from forward to rear facing with a hinged base and uses LATCH connectors or any type of seatbelt. The price regularly goes between $65 and $90.
