According to Ann, only two puppies would fit into the 21 x 21 x 28 crate and will be a "tight squeeze" (as she put it). She will look for a small crate for the 3rd puppy (which I will ship back). However, what is the maximum size for the small crate to fit in your bagage department area? I completely understand the importance of the crates and pups fitting on your plane. And, I also would hate for you to arrive and the pups/crates do not fit.
If it is okay, I will start sending you e-mails from our rescue e-mail: email@example.com
to your personal e-mail firstname.lastname@example.org
. This way I can work with communicating with you and Ann.
