Anyone used one of these...?

I have got one and it looks great but I think DS (2.4) would probably be more comfortable in his car seat.
DH is not so keen as it will be him having to lug the carseat around the airport.
I'd be interested to know if anyone has used the harness on the place and how it went? Did the cabin crew let you put it round the back of the seat? We have someimtes had issues with taking our car seat on board when cabin crew say "you cant use that" etc!
