Any CEO is going to talk things up rather than down, IATA are looking at 2024 before a return to 2019 levels. Even if a vaccine was approved today, the lead time to produce, distribute and apply it is still a few months.
The A380 has had its time and the business model needs to change. EK may end up flying to more cities using smaller aircraft such as the B787-8. KLM fly to more UK destinations than British Airways, offering connections through AMS.
Point to point between destinations will be increasingly common but connections will still be required for secondary cities. Birmingham to Delhi might go direct but Liverpool to Bangalore would connect through a hub.
A fleet comprising B787-8/9/10 and A320/1/LR would make sense going forward as these types are more flexible, cheaper and open up cities which can’t fill a B777. Major city to secondary city will increasingly bypass hubs as these routes can now be done with the B787. Secondary city pairs still require hubs but need smaller aircraft.
The experience of the past few months, and market projections going forward are likely to result in a serious rethink of the fleet mix, the other two have much more flexibility when traffic plunges.
