Are you talking comercial flight? Are you ging with him/her?. just get him/her used to the kennel, the first flight my Chocolate did back in 1991 was a trip to Spain, he did very well going and coming. Get one of those no spil water bowls, or that will just end up all over inside. Don't sedate either, they will cope better without.

Iwill be going to Kansas labor day weekend to pick my new Pup up, and that will be his first flight, but he will only be in thekennel for 3.5 hours hops, then able to get out and do his thing.
