This Gawker article summarizes the findings pet-travel related findings of the Air Travel Consumer Report from the DOT. While Delta flies more pets than most airlines (according to a Delta spokesperson), only .2% of the animals they carried were injured or died. Still seems pretty high to me.

The report, available online, confirms that 19 of last year's 35 in-flight pet deaths happened on Delta planes. That's up from 16 in 2010. The second most deadly airline for pets was American, with 5 deaths. Delta also led the pack in terms of pet injury, with 5 out of 9 total incidents occurring on Delta flights.
