since I've never flown with my dog before and I'm going to have to in about 2 weeks, I decided I'd ask here... if you're flying with a small dog in the cabin and will have to lug it around the airport with you while you're on a layover, does the dog have to stay in its kennel or can it be let out on a leash? Does it vary by airport? I've searched a lot, but haven't been able to find any airport policies on this... all I've found has to do with how they are treated as luggage by the different airlines. Letting the dog relieve his/herself also has to be done outside security, outside the airport, right..?
