The longest and shortest Boeing 737-800 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
3,777 mi
Brasília – Orlando (BSB–MCO)
954 departures · 91% load
Flown by VRG Linhas Aereas S A. 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 · 107 departures · 49% load
Flown by Alaska Airlines. About 23m of block time, most of it connecting traffic feeding the hub.

Who flies the Boeing 737-800
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 737-800 fleet?
Age is measured from each airframe's delivery date — the FAA airworthiness date where available, otherwise the manufacturer's. Bars share a fixed scale across every fleet page, so two carriers can be compared directly.
