The grounding of Boeing Co.'s 737 Max after a pair of accidents killed 346 people might seem an unmitigated disaster for the world's airline industry. Look at flight data, though, and you can glimpse a grim benefit supporting carriers' bottom lines.

To see why, it’s worth remembering just how crucial the 737 and its arch-rival, the Airbus SE A320, are. Each plane family constitutes about a third of the roughly 24,000-strong global passenger airline fleet. Other aircraft put together – including all wide-body planes like the 747, 787, A330 and A380, turboprops and smaller jets like the Bombardier Inc. CRJ – make up the remaining third. According to Boeing, a 737 takes off or lands somewhere in the world every 1.5 seconds, and there are about 2,800 in the air at any one time.
