The United Airlines Boeing 757-300 carries 234 passengers across United First + Economy Plus + Economy. Power and Wi-Fi are available on this aircraft. Every seat is rated below, so you can see which have the legroom, the window alignment and the quiet — and which sit next to a galley or lavatory.
The seats rated best on this map are 1A, 2A, 2F, 3A, 3F, 4A. Another 90 seats are rated best or good. Look for exit rows 21, 22 and 64 extra-legroom seats for the most room.
Seats rated avoid on this map are 18A, 18F, 32A, 32B, 32E, 32F. Another 30 seats are rated avoid. These are usually the back rows near the galley and lavatories, or middle seats with no window or aisle.
The 757-300 is a long aircraft with a single aisle, so deplaning the rear section takes time. If you have a tight connection, pay for a seat in the front half of Economy or Economy Plus — it can shave ten minutes or more off your time to the gate.
The seat product is similar — a domestic-style recliner in a two-two layout. The main difference is that the -300 is a longer aircraft, so First feels less isolated from the rest of the cabin on a proportional basis.
The 757-300 is primarily a domestic aircraft for United, operated on high-demand domestic corridors. Its range is shorter than the -200, making it less suited to transatlantic routes.
