The reports I have seen have said Stansted. Not even sure one off charter flights using the terminal are allowed due to the seasonal passenger air transport limit imposed by ACL where batches of slots were allocated to airlines at the start of winter 2019 as part of the passenger capacity constraints to limit passengers to 18 million.
The same is true for the summer where the existing airlines that operated out of Luton were allocated so many passenger seats for the season. As they took them all there was nothing left for anyone else.
