That's a shame, although I'm not convinced 26th March will stick anyway - 7 weeks away. Feels like they need at least another 1 x 777-300s to come out of Cardiff to service that route - and there are none there at the moment.

Maybe they feel they have enough CS -300s in the fleet, or BA intend to "downgrade" a different route to CW


EDIT: I understand from another thread that BA are planning to take delivery of more 787-10s in March. That might free up some of the 777-300s being used on those routes, so maybe late March for BGI will be correct.
