I sent a puppy out to Finland 4 years ago. She went cargo with Finnair from Heathrow, cost £220. Whenever I spoke to their cargo dept they were very helpful. The tricky thing was calculating the eventual size of the crate acceptable to the airline at the time of travel and I took the pup to Airpets a week before and got one from them, cost £63. The puppy was less than 3 months old so didn't require a rabies jab.
From my notes I still have I'd written down the following:
Pup needs Health certificate IATA/vet certificate reqd for pups under 12 weeks old stating dog is fit for transportation (same thing?)
Microchip & I'd done the tattoo
Transfer KC reg / Export pedigree
and on the crate I had to tape on a letter stating the dogs ID, breed, breeder, saying the animal had been kept on my premises since birth and hadn't had contact with wild animals.
Evira is the Finnish website to look on for further info.
It all seemed pretty straightforward at the time, the worst bit was taking her to Heathrow at silly o'clock in the snow. Flight was on time, she travelled well & I got a phonecall when she arrived (was 1st off the plane).
