Complimentary Fare Upgrades - Moveable?

[Homer]

My Velocity membership anniversary is in four days so I have four complimentary fare upgrades to use by then. I understand that I can book Flexi Fares in the next four days, for travel in the future, and then have four sectors upgraded. My question is: if I subsequently choose to move the Flexi Fares (ie change the dates of travel), will the upgrades move with them (subject to availability)?

I believe you'll need to re-book them with the right availability. Providing there is the availability, the Velocity call centre should be able to take care of this (I seem to remember a similar question asked here the other day and that was the answer). If the flexi fare has changed in price, you may have to pay the fare difference too.

Wot drewbles said!

I have experienced this exactly including paying the slight increase in the flexi fare price. The upgrade stayed with me.
