Hi,

I’m looking for advice on flying internationally with my 11 year old daughter's Britax Frontier Clicktight.

We’re flying American from Chicago to Rome.

Has anyone ever had (or seen) the use of a child seat refused for an older child? I've been told this can happen despite FAA rules. If you have/did, what could have stopped it from happening? Specific paperwork, car seat manual, preauthorization from the airline?

And does anyone have any tips for flying with the Frontier given it's a big seat? I’ve been told it fits in an aircraft seat, even with some of it just over the edges of the seats so that's not an issue. I have been told that it can make the child too high and too far forward to be able to use the tray table. If so, what tricks are there to help with that? Are there portable tray tables you can buy or are they not worth it?

I’ve also been told the Frontier is uncomfortable when installed on an aircraft seats, but I don't fully get why.

Does anyone know about any of this or can offer some advice?

Thank you for any help.
