In a box in the storage compartment yes. In the cabin you are limited to lice, bacteria, viruses, tapeworms ... (I think you get the idea). In some cases you can bring a pig (husband) or a henn (wife).

Well said, cy! lol!

I didn't know that you got a great sense of humor until now. ;)

That was a funny comment.

Maybe you can sneak in a Hamster...not sure though whats the consequence if you get caught.

I read somewhere that they are special requirements and procedures for bring pets on the plane. It would be cool if they could sit beside you and play with them especially on an overnight flight.

I think we can take pets in plane on special request.They will permit us but we have to pay extra charge for that.
