I think MAN's passenger recovery may be quicker than some forecast although maybe in a different form to before the pandemic.
The likes of Ryanair / Jet2 / Easyjet will when able offer low fares to entice the travelling public back into the air. So low cost and charter to Europe will likely return quicker. A key point that has been mentioned before is that a based low-co aircraft can operate a number of flights each day offering considerably more seats / passengers / revenue than one long-haul service might do. Yes, these long-haul services are important destinations to the region and yes they will return in the longer term but the airport needs passengers to make money and I dare say it will take whatever is available when the happy day arrives that we can all travel more freely once again.
