We are moving, so have to take her with us. We are traveling on official military orders so we don't have any say with regards to getting an extended layover/overnight stay in the middle. Unfortunately us flying through Chicago means she has to fly in the cabin and going outside during our layover will not be pleasant I'm sure.

I do plan on lining her carrier with puppy pads/absorbent material and changing it often. I will have moist towelettes to clean her if she becomes soiled. I have a leash for her, although I'm not sure when/where I could use it. I plan to take her out a few times in the bathrooms to let her "stretch" her legs.

This is all I could think of, not sure what else I could be doing...?
