Delta is a dog-friendly airline and Kelly had taken the proper steps to allow her 5-year-old pup on board, so what led to this snafu? It seems that Delta's planes aren't uniform in terms of storage space available, so despite her preparations, this dog-devoted celebrity was dealt some bad luck when little Chewie's kennel was too big for the space allowed.
Luckily, a kind-hearted passenger seated in coach - where the carrier could be properly accomodated - offered to switch seats with Kelly during take-off and landing so that she could stay close to the dog and remain on her flight.
So there you have it. Even glamorous celebrities can encounter problems when flying with their pets, proving that it's best to do lots of research before you hit the skies. Double check with your airline about any possible issues that could arise, have all paperwork in order, and, like this (unpleasantly) surprised actress did, always be ready to deal with a curveball or two.
