Oh thank you! I planned to actually bring a little blanket and stuff it in my pocketbook carryon so that I could put it in the crate once we get through security... I figured Im pushing the weight limit already so I cant put a blanket in there, but I will put one in there once we get past the counter that may or may not weigh them! Thanks for the advice! This is also Dec in New England so yeah they will be chilly I bet! I'll put little sweatshirts on them!
