Hi There,

thanks for your help on this one. it did sort itself out, but i don't know how.
I spoke to British Airways again fro about 20minutes in the UK and they advised me to book a separate flight on south african airways and then claim it through customer relations services after i finished my trip. They would not guarantee I would be refunded for the flight. They would also not give this to me in writing, either would LAN. I also spoke to LAN and they said I needed to sort out the cancelled segment with BA before I could change my other flight as an error kept coming up on their system. They also said they spoke to BA who apparently told them that BA is happy to take responsibility but wouldn't do anything about it.

After much stress and arguing, I called back BA ready to demand the flight again with another agent, but when I did, my ticket had been miraculously reissued, with my flight change on the London Nairobi confirmed and also the flight from Dar to Johannesburg also confirmed.

I don't know who did it but it was also sorted - much relieved.

thanks for your help, it was really useful

Ben
