The longest and shortest United Airlines 737 MAX 8 flights
The two ends of the type's working envelope, from the routes it actually flew — not what the airframe is certified to do.
Longest route flown
3,370 mi
7h 15m block · 203 departures · 78% load
Flown by United Airlines. A long leg for a narrow-body twin — far enough from a diversion airport that the type carries an ETOPS rating.
Shortest route flown
120 mi
1h 3m block · 1,707 departures · 65% load
Flown by United Airlines. Also one of the type's busiest routes anywhere in the US — a short hop worked like a bus line.
