Well, it looks like UK has banned the 737 MAX, and Norwegian has grounded its fleet of 737 MAX. I am somewhat surprised by Norweigien’s decision since of all airlines it probably is in the least financially viable position to ground its MAX fleet. But good for it for playing it safe.

So by my count, the major operators of the 78M that are still flying theirs are pretty much North American airlines, with the exception of flyDubai.
