Tui UK adds 1.1 million seats for summer 2024 | Travel Weekly
"30,000 seats added to and from Stansted"
Sadly not an awful lot compared to other airports and remains at 2 a/c. I assume additional morning slots would be tricky to obtain even if they wanted to add additional air frames.
Changes for S24 compared to S23 include additional PFO and RHO on a Tuesday and DLM on a Thursday, all seemingly replacing AYT services which remain on sale with duplicate times. Tuesday DLM switches to a third party operator. I assume AYT will also be changed to another operator in due course, can't see that route being cancelled.
