Booked Monday's TATL WT+ flight a year ago and as (and still) Gold selected 12A/B bulkhead seats at front of cabin. Partner is silver. Checked on expertflyer today to see the seats were now marked as blocked rather than occupied. Quickly logged into MMB and found that I'd been moved to 16J/K (very back of cabin and last served) but that 12A/B were now shown as available.

Hastily moved myself back to 12A/B. But why did FLY or whatever move me in the first place. Expertflyer shows W5 availability and J9, Y9 so it's not a crowded flight.

Any thoughts anyone? Many thanks.
