The Boeing 737-700's busiest US routes over the trailing 12 months, by departures.

The longest and shortest Boeing 737-700 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

2,433 mi

Newark – Santa Ana (EWR–SNA)

5h 21m block · 1,382 departures · 91% 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

31 mi

Petersburg – Wrangell (PSG–WRG)

23m block · 565 departures · 54% load

Flown by Alaska Airlines. About 23m of block time, most of it connecting traffic feeding the hub.

Who flies the Boeing 737-700

Two questions in one table. Airframes is what each carrier reported owning in its US DOT fleet filing; seats flown is how much of the type it actually operated. They can rank differently, and the gap is the interesting part.

Airframes are the latest Form 41 filing; seats flown and share are US DOT T-100 for the type's most-flown operators — a dash means a carrier isn't among them (a freighter operator, or one that flies fewer).

How old is the US Boeing 737-700 fleet?

Boeing 737-700 — airframes by age (years)
