I expect the morning flight will always be the lower deck as they are selling to 767 capacity. The afternoon flight, sold to A319 capacity is much easier to manage with the smaller upper deck.

MMB shows aircraft type is 788 on both flights but the seatmap is not showing. Called the Gold line and they say row 10 is blocked off for now and the first row in ET is row 21 which has been allocated already for my flights.
Keep an eye on this. From what I see when the aircraft changes the seat map for CE changes at the same time but the ET seat map doesn't appear for a few more days as they work out what to do with the WT+ cabin (remember this can be used as CE if required, although unlikely). You should get the seat map 72 hours or more before the flight and be able to select a more desirable seat.
