I think all you hope for at this time is that the airport apparently has enough funding to run through 2022 and that work then starts to return after that, i don't personally think we're done with covid just yet so i remain unconvinced that next year is going to be great for air travel, although i hope i'm proved wrong.
Also heard that amazon are opening a facility at stansted which surely does not bode well for the existing freight operation, although my guess is they would have to pay a penalty to get out of the contract, but then again they seem to be money no object at this time and that would leave the airport completely on it's knees.
I'd love to be more positive but with how things stand it's difficult to be anything other than pessimistic
