Hi, could someone please check loads on BA103 on 25th July and then BA102 on 6th Aug across WT, WT+ and Club cabins?

We’re booked into WT+ both ways - the 102 has just had an aircraft change from a 788 to 789....which I’m guessing could be in the sweet spot of a potential upgrade from WT+ to Club given the 789 has fewer economy seats than the 788 and the Calgary route is a popular holiday trip in the summer.

many thanks in advance
