The_Banking_Scot,
Many thanks, I tried this once before at Heathrow and all they could do is give me the walk up fare which was around £900 more!
It's a shame because althought WT+ is worth £150 more IMHO, it certainly isn't worth an extra £900!
All I'm trying to do is give them some extra money? I'm not depriving them of extra revenue as the flight is wide open at the moment!
Oh well, guess I'll never understand airline ticketing polices!
Thanks again
Benjurs
PS - Do you reckon I may get more help on the FT website?
