How the live map reads

There is no cabin diagram on this page

2LNR doesn't publish stored seat diagrams or per-seat comfort ratings, for this aircraft or any other, and it won't invent them. What it has is the live seat map for a specific UA flight and date, read at the moment you ask, on Pro. That's a different thing from a drawing of the type, and it's the only version that survives an aircraft swap. If a diagram is what you came for, a maintained library such as AeroLOPA is the right tool.

What's on this page

Every nonstop route United Airlines currently schedules the Boeing 777-300ER on, taken from the flight schedules 2LNR collects continuously. The aircraft is a Boeing 777-300ER, a widebody. UA files it as 77W in its schedules; those spellings are treated as one aircraft here rather than as separate types.

The longest of those routes is Manila (MNL) to San Francisco (SFO), about 6,980 miles. The median route runs about 5,110 miles, so most of this aircraft's flying is a good deal shorter than its longest leg. Distances are great-circle between the two airports, rounded to the nearest ten, rather than the track a flight files.

These are the aircraft names in 2LNR's own reference for UA, not seat counts and not a cabin layout. We don't refresh that reference on a schedule, so we don't claim a date for it. Configurations change with retrofits, and an airline can assign a different aircraft on the day, so treat this as context rather than as what you'll board.

Frequently asked questions about the UA Boeing 777-300ER

Where does United Airlines fly the Boeing 777-300ER?
On 29 nonstop routes touching 15 airports in 2LNR's schedule data, San Francisco to Newark, Newark to San Francisco, and San Francisco to Hong Kong among the busiest. The full list is on this page, grouped by departure city, and each route opens that city pair's own page. Schedules move seasonally, so this reflects what UA currently has filed rather than a permanent assignment.
Can I see the Boeing 777-300ER seat map for a specific UA flight?
Yes, on Pro, and it is the live map for the specific flight and date rather than a drawing of the type. 2LNR scores the open seats inside your cabin, marks paid seats as paid, and can keep watching for a better one. That is deliberately different from a static United Airlines Boeing 777-300ER diagram, which cannot tell you whether 12A is free or whether the aircraft was swapped.
Is the Boeing 777-300ER the only aircraft on these UA routes?
No. A route appears here when UA has scheduled the Boeing 777-300ER on it, and most routes see more than one aircraft type across a season or even a day. That is exactly why 2LNR reads the map per flight: the honest answer to which cabin you will get is a per-departure answer, not a per-route one.
Does 2LNR have seat ratings for the United Airlines Boeing 777-300ER?
Not as a published library of per-seat comfort ratings for the Boeing 777-300ER, and this page will not invent them. What 2LNR scores is the seats actually open in your cabin on your UA flight, so the answer is a seat you can select rather than a general opinion about a row. For browsing a Boeing 777-300ER cabin layout on an aircraft you have not booked, a maintained diagram library such as AeroLOPA remains the better tool.
How far does the Boeing 777-300ER fly for UA?
The longest of the 29 routes UA schedules it on is Manila (MNL) to San Francisco (SFO), about 6,980 miles measured great-circle between the two airports rather than as flown track miles. The median route on this aircraft runs about 5,110 miles, so the long one is the exception rather than the pattern. Range on the day depends on load, winds and the specific variant, so treat this as the shape of the flying rather than as a capability figure.
