It seems they are only useful to use for flights, I have always used them for F upgrades in the past, but anything that gives BA any revenue in the future frankly churns my stomach!
It is nothing too substantial, they have done things to irritate me over the years but recently I asked them to change a date on a flight because of a very valid reason and they refused to do it saying I would have to purchase another ticket and forego this one, bearing in mind it was a Sydney Club fare so not a cheap ticket ( second one this month too!).
Although I appreciate a non changeable fare is just that and they are within their rights, I feel that after spending in excess of 60K with them on fares in the past 3 years a little flexibility when ones Father has been given days to live was not too much to ask for! Apparently it is.. No more money for BA from me.
Nice seat number btw
