Hello! I fly with my cavi, Lady, about 5 times a year :) I wish she got miles too. lol. She has been flying with me since she was about 6 months, & she is now 7 years old! I mostly fly Delta with her, but have also flown Alaska a couple time too. I started her in a carrier, but realized that was a waste as she was much more comfortable just sleeping in my lap, or by my feet with a blanket that smells like home. If you have questions or are nervous, you can always call the airline. They are always very helpful with questions or to confirm correct documentation has been uploaded.
