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) 40 Nonstop routes 12 Airports served 2,550 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 757-300 on, taken from the flight schedules 2LNR collects continuously. The aircraft is a Boeing 757-300, a narrowbody. UA files it as 753 in its schedules; those spellings are treated as one aircraft here rather than as separate types. The longest of those routes is [Los Angeles (LAX) to Honolulu (HNL)](https://2lnr.com/routes/lax-hnl.md), about 2,550 miles. The median route runs about 1,680 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. ## Where UA flies the Boeing 757-300 40 nonstop routes across 12 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. ### Chicago (ORD) - [Chicago (ORD) to Denver (DEN)](https://2lnr.com/routes/ord-den.md) - [Chicago (ORD) to Houston (IAH)](https://2lnr.com/routes/ord-iah.md) - [Chicago (ORD) to Los Angeles (LAX)](https://2lnr.com/routes/ord-lax.md) - [Chicago (ORD) to Orlando (MCO)](https://2lnr.com/routes/ord-mco.md) - [Chicago (ORD) to San Francisco (SFO)](https://2lnr.com/routes/ord-sfo.md) ### Denver (DEN) - [Denver (DEN) to Chicago (ORD)](https://2lnr.com/routes/den-ord.md) - [Denver (DEN) to Houston (IAH)](https://2lnr.com/routes/den-iah.md) - [Denver (DEN) to Los Angeles (LAX)](https://2lnr.com/routes/den-lax.md) - [Denver (DEN) to Orlando (MCO)](https://2lnr.com/routes/den-mco.md) - [Denver (DEN) to San Francisco (SFO)](https://2lnr.com/routes/den-sfo.md) - [Denver (DEN) to Washington (DCA)](https://2lnr.com/routes/den-dca.md) - [Denver (DEN) to Washington (IAD)](https://2lnr.com/routes/den-iad.md) ### Honolulu (HNL) - [Honolulu (HNL) to Los Angeles (LAX)](https://2lnr.com/routes/hnl-lax.md) - [Honolulu (HNL) to San Francisco (SFO)](https://2lnr.com/routes/hnl-sfo.md) ### Houston (IAH) - [Houston (IAH) to Chicago (ORD)](https://2lnr.com/routes/iah-ord.md) - [Houston (IAH) to Denver (DEN)](https://2lnr.com/routes/iah-den.md) - [Houston (IAH) to Los Angeles (LAX)](https://2lnr.com/routes/iah-lax.md) ### Kona (KOA) - [Kona (KOA) to Los Angeles (LAX)](https://2lnr.com/routes/koa-lax.md) - [Kona (KOA) to San Francisco (SFO)](https://2lnr.com/routes/koa-sfo.md) ### Los Angeles (LAX) - [Los Angeles (LAX) to Chicago (ORD)](https://2lnr.com/routes/lax-ord.md) - [Los Angeles (LAX) to Honolulu (HNL)](https://2lnr.com/routes/lax-hnl.md) - [Los Angeles (LAX) to Kona (KOA)](https://2lnr.com/routes/lax-koa.md) - [Los Angeles (LAX) to Washington (IAD)](https://2lnr.com/routes/lax-iad.md) ### Orlando (MCO) - [Orlando (MCO) to Chicago (ORD)](https://2lnr.com/routes/mco-ord.md) - [Orlando (MCO) to Denver (DEN)](https://2lnr.com/routes/mco-den.md) - [Orlando (MCO) to San Francisco (SFO)](https://2lnr.com/routes/mco-sfo.md) ### Portland (PDX) - [Portland (PDX) to Chicago (ORD)](https://2lnr.com/routes/pdx-ord.md) ### San Francisco (SFO) - [San Francisco (SFO) to Chicago (ORD)](https://2lnr.com/routes/sfo-ord.md) - [San Francisco (SFO) to Denver (DEN)](https://2lnr.com/routes/sfo-den.md) - [San Francisco (SFO) to Honolulu (HNL)](https://2lnr.com/routes/sfo-hnl.md) - [San Francisco (SFO) to Houston (IAH)](https://2lnr.com/routes/sfo-iah.md) - [San Francisco (SFO) to Kona (KOA)](https://2lnr.com/routes/sfo-koa.md) - [San Francisco (SFO) to Orlando (MCO)](https://2lnr.com/routes/sfo-mco.md) - [San Francisco (SFO) to Washington (IAD)](https://2lnr.com/routes/sfo-iad.md) ### San Luis Obispo (SBP) - [San Luis Obispo (SBP) to Chicago (ORD)](https://2lnr.com/routes/sbp-ord.md) ### Washington (DCA) - [Washington (DCA) to Denver (DEN)](https://2lnr.com/routes/dca-den.md) ### Washington (IAD) - [Washington (IAD) to Chicago (ORD)](https://2lnr.com/routes/iad-ord.md) - [Washington (IAD) to Denver (DEN)](https://2lnr.com/routes/iad-den.md) - [Washington (IAD) to Los Angeles (LAX)](https://2lnr.com/routes/iad-lax.md) - [Washington (IAD) to San Francisco (SFO)](https://2lnr.com/routes/iad-sfo.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 757-300 **Where does United Airlines fly the Boeing 757-300?** On 40 nonstop routes touching 12 airports in 2LNR's schedule data, San Francisco to Chicago, Chicago to Los Angeles, and Chicago 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 757-300 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 757-300 diagram, which cannot tell you whether 12A is free or whether the aircraft was swapped. **Is the Boeing 757-300 the only aircraft on these UA routes?** No. A route appears here when UA has scheduled the Boeing 757-300 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 757-300?** Not as a published library of per-seat comfort ratings for the Boeing 757-300, 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 757-300 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 757-300 fly for UA?** The longest of the 40 routes UA schedules it on is Los Angeles (LAX) to Honolulu (HNL), about 2,550 miles measured great-circle between the two airports rather than as flown track miles. The median route on this aircraft runs about 1,680 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.
