Rocky was with me in cabin about 3 times. I had a soft pet carrier with me and it went really well. I was really lucky as I was always allowed to either have him in his carrier on my lap or on the seat next to me, so never had to put him under the seat. The flight was really short though (1.5 hours) and I have to say that he did seem nervous.
I would defo have your chi get used to the carrier beforehand. Its a big advance that Rocky loves his carrier, as he gets into it straigth away when I get it out of the closet.
I have to say though that a 14 hour flight does seem quite long and I can't imagine flying for that long with Rocky being stuck in a "small carrier". I would try to split up the flight into maybe 2 flights with a day break inbetween somewhere (not sure if that's even possible). Even for us 14 hours are long and borring, but for an animal it seems even worse.
