I have just had a push-message that a flight in a couple of weeks, AF1238 CDG-VIE, is now operated by BT. No change in flight number. Website has not caught up, or in any case, still says operated by AF. Does anyone know if this is a wetlease or what? I know there was one in late 2025.

My only issue would be if it involved the hassle of 2E-2B as it would be less-than-ideal.
