Congrats to those in the pool that have got courses.
BA have only released start dates for Feb and Mar for those looking to move seats within the company. I guess those hold-poolers who have just got slots are back filling courses where internal candidates cannot be released from their own fleets. I suspect a similar process will happen every few months as the course programme is put together.
One word of warning though to those going to the 747. For the first 5 years in BA you have an engagement freeze which means you are their b***h and they can do with you what they want. As the 747 is due to retire in 2022 there is the danger that you could be directed (forced to go) to the mini-airbus. Its unlikely but it is a possibility. Just a note of caution.
All the best
