The airport is unlikely to see more than 3 LARGE aircraft at anyone time any way.
if we did get a link to the USA again the aircraft would be gone before EK arrived and if when we get the evening EK it will Be early evening again nothing else around.
unless TUI/TCX decide that for summer 2020 they basing 3 each daily of A330/787 (highly unlikely) then there isn't need to get bigger stands as not needed.
the bulk of extra flights which we will see will be on 320/321/737 aircrafts
