It is debatable, given the significance of the changes, whether the notice given can be regarded as 'reasonable, as appropriate in the circumstances'. People will already have started to replan qualification for the following year and you would have thought that, introducing the new system for 26-27 rather than 25-26 (or offer the possibility to members to requalify in accordance with both old and new rules for 25-26), would be what is required to constitute reasonable notice within the meaning of clause 28, especially for members who are consumers and in relation to whom, therefore, clauses must be read subject to a good faith requirement with respect to the professional (viz. BA in this case).
I'm in exactly this boat. I have a QR far east return booked for August that should have locked in my Silver status until March 2027. It will no longer do that. I, arguably, booked the trip in good faith based on the information BA presented to me at the time and am now disadvantaged as a result. Have sent in a moan to customer relations but don't expect anything to happen. I accept, to an extent, that this is the game we play, but it doesn't feel entirely reasonable.
By way of example, Alaska has messed with partner earnings for 2025 but is still allowing retro-claims at the old rates for those who booked travel pre-announcement, which feels fair.
