Hi! Just passing by, had to comment. They don't advise taking carseats on the plane, take small snacks, books, washable makers, she can colour in the tray and then wipe up with wipes. worked for me, flew 6 hours when my daughter was 18 months, she was happy to read and colour and sleep. I have travelled a few times with less than 2 year olds and they generally fall asleep with the motion and noise. Good luck.
