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

Anchorage – Newark (ANCEWR)

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

Denver – Eagle (DENEGE)

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.
