Well all the dogs I shipped were by Delta. The reason is that they have pressure cabins in the " cargo hold" so the dogs didnt get too cold etc. If they small, each of you could take one dog and carry on with you to be under your seats. ( mine were too big obviously). Try delta first. Remember they can NOT wear metal id's and ask the steward to bring water to give the dogs. Try for a direct flight- but if carry on, you can just move flight to flight. While the dogs have to be in crates, several trips I found people are curious and the stewards, and dont even care if you take them out to sit in your laps. If you need anymore help, pm me..
