It looks like they've just rolled over the Summer 23 schedule for S24 for the sake of banging something up on sale. The BHX route schedules for based aircraft aren't there, the new SOU routes launched in winter aren't continued into the early part of S24 (assuming they will be) - it just appears to be a rush to get flights on sale, presumably to avoid Jet2 and TUI who have both been on sale for quite some time for S24 hoovering up all of the bookings to easyJet's detriment.
