We are going on vacation fairly soon and are thinking about bringing our sons car seat on the plane. We have the Britax Allegiance which is approved to use on planes however I am looking for real life experience. Does it actually fit into the plane seats? I dont want to get to the airport only to find out it doesnt fit.

Thank you,

You probably won't have a problem with it rear facing at an upright angle in most planes, unless they have very very short pitch. It might be uncomfortable to sit next to forward facing but would likely fit as long as you're in a row where the armrests lift.
