At this point A class has been affected negatively. If this holds then yes this event has affected the ability of high spending members to use their benefits.
Hmmm....I made a contract with the airline which cited a "guaranteed" airfare.
"High spending members" (whatever that is suppose to mean) have no such guarantee with regard to their loyalty benefits, since their benefits are subject to availability, which can be manipulated by the airline for any number of factors and a decision making process, which are are NEVER transparent to the loyal member. As far as I can tell as the member of numerous FF schemes, the reward seat inventory in CX is one of the worst as a default position. You know this.
Unless you're on the CX Board / Executive you'll never know the real position!
So don't denigrate those of us that scored (comments about "gnashing teeth" for example) because you expected something you were never entitled to only get sucked in by.
There sure is some bad and biased attitude on this part of FT from inappropriate sources. Nasty stuff.
