I met a maintenance supervisors/leader type for United Airlines last weekend. He said that the grounding of the 737 Max was annoying, but manageable.

An plane sidelined for maintenance can be serviced more quickly, and returned to operating status faster than it was initially scheduled to be back in the air.
