I believe the Max aircraft will fly the same programme every week, and will not be interchangeable with the 738's, the Max will operate most of the Egypt & Cape Verde flights.
The 3 Edinburgh flights will be operated on "W" patterns by the ABZ or NCL based 738's
The leased in 787 at Manchester, I think is due to be a "spare" aircraft, so not included in my breakdown, and the Air Tanker A330 is not showing in any schedules at present, not certain if it might operate extra flights, or maybe replace a 737/763/787 , hence schedule it always subject to final confirmation.
As already mentioned, there is still a query about the SmartLynx A320's/A321's, and if they have enough aircraft/crews to go around for the summer.
