The May, 2007 Airline Pet Travel Report contains pet incidents for the month of March, 2007.
Continental reported two deaths. The first was a 10 year old Siberian Husky which was found deceased upon arrival in San Antonio, TX from Newark, New Jersey. A necropsy indicated the cause of death as a pre-existing heart condition. The second death was 14 year old cat with extensive pre-existing health conditions. Continental again does a good job of providing detail in their reports.
Northwest reported a cat who was injured when it escaped from its kennel, the cat was quickly captured, but suffered a scratch on its face. The cat was accepted in a folding kennel and without zip ties on the kennel door contrary to Northwest policy.
United reported the death of a Lhasa Apso upon arrival in San Paulo from Washington Dulles. The kennel was intact and the other dog belonging to the same owner arrived safe. Due to the time required to return the dog to Washington, no necropsy was performed.
