Norwegian appears to be one of the two airlines that fly to the UK with the aircraft, and they have taken the consequence and grounding their 737 MAX-8 fleet as well.
Air Canada flies from Halifax to London on a 737 MAX-8[1]. I flew it in Dec shortly after the Lion Air crash.
I believe this will affect Air Canada, which flies 737 Max 8 on several Canada -> UK routes.
That sounds painful for passengers.
Eight hours in a narrow body; uggghhh!
That doesn't seem so much different from a transcon flight in the US, which is mostly no big deal.
Even though a narrow body isn't as conformable, I'd much rather fly direct as generally the alternative is two flights - a narrow body to a hub and then a heavy across the pond.
Long-haul on a narrow body is fine as long as the seats are good. QR used to do an all-J A320 LHR-DOH which was a great way to travel.
It’s banned from UK airspace, so US flights to Europe are affected (at least flights from lower latitudes)
