No you can not give them anything to help them travel when flying.
Anyway...................................

I had a call today just before I had to go out. I have found a family who are going to collect them on thursday. They sound very nice and are looking forward to having them, plus they do not live too far away so Charlie should be okay. I will let you all know how it goes as they are going to keep in contact with us, even when we are in NZ.
