I have spent ages trawling the internet to try and find out which car seats comply with BA's policies, but it seems no one has actually answered the question saying what seat they have used successfully!
And BA won't comment.
I see the Britax Prince fits within the 45cm x 45cm dimensions and is suitable for a 2-point lap belt as needed, but being a seasoned flyer, I'm a bit worried about how to actually fit the car seat with an airplane seat belt. It fastens in the middle of your lap, not at the side like a car lap belt, so can you actually secure and tighten these?
Anyone out there been there and done that? Can you please advise??
