Looking at post 9-11 I'd say Ryanair will take their aircraft and maybe even upsize their order with whatever becomes available for cheap now. Given that the FAA clears the MAX to fly again what I expect to happen.
Aside from that widebodies are cheap now. This might be the moment for Ryanair to launch their separate long range brand for transatlantic flights. There will be more demand for cheap flights as many people still need to travel but don't have money to burn for luxuries anymore.
