We survived 2-15 hour flights with 2 kids under 2. If you may like to know, it wasn't bad at all.
Olivia did amazingly. She did not cry, she also did not sleep... hmmm... I didn't mind that she didn't sleep because she was very happy the whole time + it worked out for us, cause with the time difference, it made her adjust right away.
Marky, as always, was a great sport. He's so fascinated with planes and he's super curious with just about everything, that he keeps entertained pretty easily. It's just more how we handle tiredness and having to answer absolutely every question there is. He needs to know everything about everything. He's at that age, I guess...
