The airport is not at capacity by a long way since the pandemic. TUI have operated from North for many years. As I said the ACMI based aircraft for TUI have been based in South before so no real issue. You are seeing an issue where there is really nothing to see. With 79 based aircraft it is no wonder EasyJet have to split their operation in the same way as BA has to at Heathrow between terminals 3 and 5.
