I think no airline can tell you with any degree of certainty what routes they will operate in Summer 2021. IF Covid becomes a part of history through burning itself out and vaccine then there will be lots of routes. However the big Caveat is will people be willing to travel. IMHO the answer is not yet.
Flying somewhere is about confidence as post 9/11 showed in Europe, then it was against a visible threat. now it is an invisible one.
People are influenced by others. So if Kevin and Sharon do a couple of weekend breaks and keep telling friends the message from them and others is flying is OK. Getting the same message from Del and Tracey etc etc then confidence will start to rise as people think "If they can then we can". Knowing someone who has done it an arrived back safe and well is key.
Confidence is fickle, as post 9/11 the AA crash on Long Island almost brought US Aviation into an immediate shutdown.
I do feel many marginal routes where airline only really makes money for 4 months a year but it covers most costs rest of year are under threat in 2021. Until population are back treating travel as before then airlines will chop and change routes all the time.
It is likely that during 2021 that routes will appear and disappear all the time but airlines will be in the driving seat, airports can not afford to be choosy as the local economies they serve will need as many travellers in to sustain jobs as possible.
