This is an interesting site I think/ It lists all airlines and the number of injuries/deaths they have had when transporting animals.
I suppose the reassuring statistic from the ATA (Air Transport Association) is that only 1 per cent of the 500,000 animals transported by plane each year suffer any complications which can range from the very minor to the major.
From a press release:
One shouldn't judge an airline only on the basis of numbers of deaths or injuries. If you download the reports for a given airline often the injuries were inflicted by the animal on itself (eg trying to chew thru kennel bars causing mouth injuries) and deaths seem very often to be from the stress of the flight causing death due to a pre-existing cardiac condition. Autopsies are performed on the animals that died.Complications range from minor issues including
unapproved kennels, lack of health certificates, and missed
connections to more serious problems, such as loss, injury, or death
of the animal. Most injuries to animals in transit result from
mishandling by baggage personnel, severe temperature fluctuations,
insufficient oxygen in cargo holds, or damage to kennels.
Note that foreign airlines do not have to make these reports.
