Gill,
Here is the reply I have just received from Balkan.
Hi Pete
Thanks you for your e-mail.
I was starting to think you have forgotten about us. Just to let you know that we will advise the airline and our check in staff that the following passenger will be carrying an extra 20kg free of charge.
If you do have any more passengers looking to help, just e-mail over the details and we will take it from there.
thanks pete parking my car at the airport so worst case scenario is I have to put it back in the car if they query it, but hopefully all being well a nice load of jumpers, scarfs, jackets hats on their way over, wish I had a bigger bag to put them in, or organised it sooner, my mistake and the worst part the orphanage;s loss which I am kicking myself for...
