2 out of how many??
Southwest said a couple days ago that it had operated around 30,000 flights for its MAX fleet, and although Southwest has the largest MAX fleet at 31 aircraft, it has less than 10% of the 350-odd MAXes delivered so far, so I think it would be fair to guess there have been probably several hundred thousand commercial MAX flights. As mostly short- to medium-haul aircraft, narrowbodies like the 737 and A320 families tend to see a lot more takeoff and landing cycles per day than larger, more long-range aircraft.
