Hi we had our 2 cats fly over with Thomas Cook in 2010...they went in the cargo compartment in a crate that had a divide in the middle so they could see each other but were seperate, they are brother and sister and sometimes fight! we picked them up from TO and they were fine, we did use an agent as that is what the airline requested. It is always best to check with individual airlines as they all have different protocols.

Oh and no way could we have left them behind...the expense was well worth having our babies here with us...in fact they have helped us to make the transition here a little bit easier!
