On a fleet assignment this narrow, knowing the route is knowing the aircraft. This page lists those routes; the cabin itself is a live read on a specific flight rather than a stored drawing.

[Get started free](https://2lnr.com/login) [The whole UA fleet](https://2lnr.com/seatmaps/ua.md) 28 Nonstop routes 14 Airports served 6,980 mi Longest route Per flight How the live map reads ## There is no cabin diagram on this page 2LNR does not publish stored seat diagrams or per-seat comfort ratings, for this aircraft or any other, and it will not 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 is a different thing from a drawing of the type, and it is the only version that survives an aircraft swap. If a diagram is what you came for, a maintained library such as [AeroLOPA](https://www.aerolopa.com/) is the right tool. ## What is 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)](https://2lnr.com/routes/mnl-sfo.md), about 6,980 miles. The median route runs about 4,700 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. ## Configurations recorded for UA The configuration United Airlines records for this aircraft. - Boeing 777-300ER These are the aircraft names in 2LNR's own reference for UA, not seat counts and not a cabin layout. The reference is seeded rather than refreshed on a schedule, so no currency date is claimed 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 will board. ## Where UA flies the Boeing 777-300ER 28 nonstop routes across 14 airports, grouped by departure city. A route appears here when UA has scheduled this aircraft on it; most routes see more than one type across a season. ### Brussels (BRU) - [Brussels (BRU) to Washington (IAD)](https://2lnr.com/routes/bru-iad.md) ### Dubai (DXB) - [Dubai (DXB) to Newark (EWR)](https://2lnr.com/routes/dxb-ewr.md) ### Frankfurt (FRA) - [Frankfurt (FRA) to Newark (EWR)](https://2lnr.com/routes/fra-ewr.md) - [Frankfurt (FRA) to Washington (IAD)](https://2lnr.com/routes/fra-iad.md) ### Guam (GUM) - [Guam (GUM) to Honolulu (HNL)](https://2lnr.com/routes/gum-hnl.md) ### Hong Kong (HKG) - [Hong Kong (HKG) to San Francisco (SFO)](https://2lnr.com/routes/hkg-sfo.md) ### Honolulu (HNL) - [Honolulu (HNL) to Guam (GUM)](https://2lnr.com/routes/hnl-gum.md) - [Honolulu (HNL) to San Francisco (SFO)](https://2lnr.com/routes/hnl-sfo.md) ### Manila (MNL) - [Manila (MNL) to San Francisco (SFO)](https://2lnr.com/routes/mnl-sfo.md) ### Newark (EWR) - [Newark (EWR) to Dubai (DXB)](https://2lnr.com/routes/ewr-dxb.md) - [Newark (EWR) to Frankfurt (FRA)](https://2lnr.com/routes/ewr-fra.md) - [Newark (EWR) to Rome (FCO)](https://2lnr.com/routes/ewr-fco.md) - [Newark (EWR) to San Francisco (SFO)](https://2lnr.com/routes/ewr-sfo.md) - [Newark (EWR) to Tokyo (NRT)](https://2lnr.com/routes/ewr-nrt.md) ### Rome (FCO) - [Rome (FCO) to Newark (EWR)](https://2lnr.com/routes/fco-ewr.md) ### San Francisco (SFO) - [San Francisco (SFO) to Hong Kong (HKG)](https://2lnr.com/routes/sfo-hkg.md) - [San Francisco (SFO) to Honolulu (HNL)](https://2lnr.com/routes/sfo-hnl.md) - [San Francisco (SFO) to Manila (MNL)](https://2lnr.com/routes/sfo-mnl.md) - [San Francisco (SFO) to Newark (EWR)](https://2lnr.com/routes/sfo-ewr.md) - [San Francisco (SFO) to Shanghai (PVG)](https://2lnr.com/routes/sfo-pvg.md) - [San Francisco (SFO) to Taipei (TPE)](https://2lnr.com/routes/sfo-tpe.md) - [San Francisco (SFO) to Tokyo (NRT)](https://2lnr.com/routes/sfo-nrt.md) ### Shanghai (PVG) - [Shanghai (PVG) to San Francisco (SFO)](https://2lnr.com/routes/pvg-sfo.md) ### Taipei (TPE) - [Taipei (TPE) to San Francisco (SFO)](https://2lnr.com/routes/tpe-sfo.md) ### Tokyo (NRT) - [Tokyo (NRT) to Newark (EWR)](https://2lnr.com/routes/nrt-ewr.md) - [Tokyo (NRT) to San Francisco (SFO)](https://2lnr.com/routes/nrt-sfo.md) ### Washington (IAD) - [Washington (IAD) to Brussels (BRU)](https://2lnr.com/routes/iad-bru.md) - [Washington (IAD) to Frankfurt (FRA)](https://2lnr.com/routes/iad-fra.md) ## Related - [The whole United Airlines fleet](https://2lnr.com/seatmaps/ua.md) - [Where UA flies: the United Airlines route map](https://2lnr.com/routes/airlines/ua.md) - [How to read an airline seat map](https://2lnr.com/guides/airline-seat-maps.md) - [An honest SeatGuru alternative](https://2lnr.com/compare/seatguru.md) ## Frequently asked questions about the UA Boeing 777-300ER **Where does United Airlines fly the Boeing 777-300ER?** On 28 nonstop routes touching 14 airports in 2LNR's schedule data, San Francisco to Newark, Newark to San Francisco, and Manila to San Francisco 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 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 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 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 28 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 4,700 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. ## See the seats on your UA flight Free to start.
