The Middle East 3 could become the ME 1.5. A merger between EK and EY with the routes rationalised would make sense, operations could continue from both home airports, which in terms of travelling time aren't much further apart then LHR and LGW. Dubai has the brand, Abu Dhabi has the money and the oil. In the aftermath of COVID-19 there will be reduced demand for long haul travel and important markets such as India will take an extended time to be at an acceptable level of risk. Once travel opens up again, direct flights will be preferable rather than connecting ones where pax mix with others from all over the world. If non stop isn't possible, then a simple refueling stop with a crew change and continuing on the same aircraft could be the new normal. Travel "bubbles" such as the one being proposed between Australia and New Zealand would severely limit hub airlines which rely on connecting pax. An airport might be restricted to transits between virus clear countries and couldn't mix flights with those from countries still virus affected for example.
Qatar Airways will be badly affected as it is a hub airline with no domestic routes and very little origin/destination traffic, they need a recovery in the long haul premium sector which will be the last area to pick up. The blockade was already causing substantial losses and the airline isn't as integral to the country as EK is to Dubai or CX to Hong Kong. With depressed oil prices there may be a limit as to how much money the rulers will put in if they can't see any payback. The airline might downsize to what is sufficient to fly the migrant workers in and out, and to take the locals shopping in LON/PAR/NY, similar to Saudi Arabian or Kuwait Airways.
