I think that there is no comparison with any other airlines in the world, those ME carriers are the best option for travellers in terms of quality, safety and network so I guess they will never stop being the most convenient option for years to come
No mate. It is cost and geographical location that makes the ME carriers sometimes the best option.
Long haul business travel will be the hardest hit. That will be a serious issue for any airline that relies on this segment, but probably even more for the ME3.
However the ME3 will continue to be a hub. Maybe not as huge as it was a few months ago. Maybe we see one airline not continuing under its current name or in its current form. Nevertheless the hub function will stay.
