It would be foolish to believe that MOL would abandon his flight crew. No pilots no airplane flights, no revenue.
Not that I have any information or inside knowledge, but I expect that they will pay maintainability salary to all crew whilst the emergency continues. Knowing that FR have bags of cash, better placed financially I believe than any other Airline serving Europe, they will emerge and take up the vast majority of pax soon as the panic finishes. In fact the delayed max was a god send to them as their expansion plans were binned. They have Germany, Malta and Poland bases with low operating cost.
I would wager a reasonable amount on FR devouring the rest of us, I mean compared to them we look like dinosaurs. They aren't around now.
