United Airlines 757-300
Overview
The Boeing 757-300 is the stretched 757, packing 234 seats into a narrowbody frame — United's highest-density single-aisle jet. With 21 aircraft, United is the largest operator of the type, flying it on high-demand transcontinental, Florida, and Hawaii routes.
The 757-300 is still flying in 2026, but United has begun gradually phasing out its 757 fleet across roughly 2026–2028. A321neo and Boeing 737 jets are backfilling this domestic flying, while the long-range A321XLR takes over the 757-200's thin transatlantic routes.
Seat Configuration
| Cabin | Seats | Layout |
|---|---|---|
| First | 24 | 2-2 |
| Economy Plus | 54 | 3-3 |
| Economy | 156 | 3-3 |
WiFi & In-Flight Entertainment
WiFi is mixed across the fleet — a blend of Viasat Ka-band, satellite Ka-band, and Ku-band. All 21 use personal-device entertainment (PDE), with 110V AC power at every seat. As the 757s are being retired, they are not expected to receive United's new Starlink WiFi; the A321neo jets replacing them carry it instead.
Routes & Hubs
High-demand domestic routes — transcontinental, Florida, and Hawaii — where the 757-300's 234 seats make it ideal for peak-demand flying. As United phases out the 757, the A321neo family is taking over much of this flying.
