Well I'm back from visiting my Dad and Jeffrey was right, Thanks Jeffrey.
I found a decent solution, recommended by a friend, in booking with Cyprus Airways. They were no-where near as limiting on what we could bring across.
We spoke to Cyprus Airways in UK before travelling who said there would be a scale of additional charge if we went over our allocated allowance, but we were welcome to take what we wanted.
We went armed with 2 massive cases each and a cheque book. We took a deep breath and check-in and... No additional charge!
Got everything to Dad's new place for Zero extra cost and all arrived intact. I've booked again already for later in the year, but my baggage will be a little lighter then!
Mark.
