We have only flown dogs 6 times, but everything has always been ok - just had one problem when Tex went to Cleveland (from San Diego) with my husband for a show in Dec. before 9/11 - the connecting flight from Pittsburgh was snow delayed. Bob spent the night in the Pittsburgh airport while Tex was comfy in the airport kennels. The next day they didn't get Tex to the plane in time and they called me to tell me they had my dog in Pittsburgh. I said, "You have my husband too!" and they explained that Tex had missed the flight - did I want them to put him on the next flight or would I pick him up? I informed them that driving from San Diego to Pittsburgh to pick up the dog would be a bit difficult, so please put him on the next flight! Duh… they called me, didn't they notice they were calling across the country? But it worked out fine, Tex was there about an hour after Bob... poor dog really had to pee but was otherwise ok.
