I agree with Veifera, the puppies look A LOT bigger in pictures than they actually are in person. I was pretty surprised at how teeny, tiny Otto seemed face to face. I flew with him from Chicago to Boston. Most exciting trip I ever took : ) . .. it was literally there and back with a short lay over in between. My dad flew with me and we played with Otto outside while we waited for our flight back. Who are you flying with? I chose Jet Blue. They are extremely pet friendly. I used this http://www.wag.com/dog/p/bergan-comf...r-black-108662
carrier. The flight attendant wouldn't let me take him out of the carrier, however, he did let me put the carrier on my lap and unzip the top part where he could put his head out. (I tried that but Otto managed to squeeze his way out twice! So I just put my hand in and pet him during the ride).
You don't need to by anything too fancy or expensive, you will probably only use it this one time! WAG.com offers 15% off to first time users and I believe free 1-2 day shipping for all orders over $49
I also agree with Zigzag, you should speak with the airline and find out exactly what the rules and regs are.
A couple quick tips. If at all possible, have someone go with you. Juggling a purse, taking your shoes off, and holding a puppy are all very difficult with out someone else there to pass your puppy off to.
Also, definitely have him out of the carrier as much as possible. We went to Chicago in October, and granted it was a beautiful day, he got very, very hot while in the carrier standing in line to go through security..
Lastly, pack LIGHT! Especially if you are just going there and back! Good luck and have fun!!! These dogs are amazing, they will make you want to pull your hair out at times, but in the end it is all worth it. You will know what I mean in about 8 months! ;D
