Very interesting - many thanks

Mrs. SFU? NFW! and I are currently booked in J for 30/09 but, given the 16 hours and 5 minutes journey time, were hoping to MFU... While we're both GCHs, I doubt the op-up fairies will smile on us given my rapidly declining CIV on what I expect is a v.GCH-heavy route!
It's almost a shame that BA will "give" the seat away when they could have reduced their mileage liability... However, I doubt the lucky recipient will think as such!
Plus, the last thing I'd want on BA is a space-available upgrade scrum, as per our American chums...
