Hi,
I am surprised (though happy) that you have managed to get a fare outside of UK in UK. I also tried to get an ex WAW fare priced in the UK but was told it had to be priced at the UK price.
I also tried getting my TA to organise the ex WAW price in the UK but she only got as far as the booking stage and was told that I would have to pay the full UK price.
I hope the rules have changed as it was much more difficult to get it through a BA external local office.
Is there a possibility though that the GIB fares may be an exception due to its links to the UK?
In any case lets us know Dave_C if you manage to get the ticket in hand as it will set a precedent many of us will follow-up on.
Cheers
J
