# Sichuan Airlines seat maps: which aircraft 3U actually flies

In 2LNR's schedule data, Sichuan Airlines (3U) flies 6 aircraft types across 138 airports: Airbus A320, Airbus A321, and Airbus A320neo. Knowing which one operates your departure is the first thing to settle before you pick a seat, because cabins differ far more between airframes than between rows. Each aircraft below opens the nonstop routes 3U flies it on, with the longest of them and the configuration on file.

## The Sichuan Airlines fleet, as actually flown

Aircraft types 3U currently schedules on its own metal, each with the nonstop routes it operates, how far those routes run and the cabin configuration 3U records for it. Regional flying under the 3U brand counts as 3U metal; flights 3U markets but another airline operates do not.

Route counts are distinct directional nonstop city pairs in 2LNR's schedule data. Where an airline files a family code without naming a variant, the card reads as the family: that is what was filed, and guessing the airframe would be worse than saying so.

Distances are great-circle miles between the two airports, rounded to the nearest ten, not the track a flight actually files. A longest route is shown only where every one of that aircraft's routes could be measured, and a typical route only where most of them could; where the measurement was too thin, the figure is left out rather than estimated.

## How to see the seat map for your 3U flight

The useful version of this question is per flight, not per aircraft type.

### Add the flight, then open its live map

On Pro, 2LNR reads the seat map for the specific 3U flight and date you are looking at, scores the open seats inside your own cabin and marks paid seats as paid. It is read at the moment you ask rather than stored, so an aircraft swap shows up as a different map instead of a wrong one.

### Then let it watch

Cabins churn in the last days before departure as blocked rows release and upgrades clear. Seat monitoring re-reads the map on a cadence that tightens as departure approaches and tells you when a better seat opens, or when the seat you hold changes underneath you.

More on that in [seat monitoring](https://2lnr.com/lp/seat-monitoring.md).

### If you want a cabin diagram instead

2LNR does not publish stored cabin drawings or per-seat comfort ratings for 3U aircraft, and this page will not pretend otherwise. For browsing a layout on an aircraft you have not booked, a maintained diagram library such as [AeroLOPA](https://www.aerolopa.com/) is the right tool.

## Frequently asked questions about Sichuan Airlines (3U) aircraft

**What aircraft does Sichuan Airlines fly?**

Six aircraft types appear on Sichuan Airlines's own metal in 2LNR's schedule data, reaching 138 airports, including Airbus A320, Airbus A321, and Airbus A320neo. The full list is on this page, with the nonstop routes each one operates and the recorded cabin configuration where there is one. Regional flying under the 3U brand is counted as 3U metal; flights 3U markets but another airline operates are not.

**Does 2LNR publish 3U seat maps by aircraft type?**

Not as static diagrams. 2LNR reads the LIVE seat map for a specific 3U flight and date, which is a different thing from a stored cabin drawing: an aircraft swap shows up as a different map rather than a wrong one. If you want to browse a cabin layout for an aircraft you have not booked, a maintained seat-map library such as AeroLOPA is the right tool, and this page says so rather than pretending otherwise.

**How do I see the seat map for my 3U flight?**

Add the flight to 2LNR and open it. Pro plans pull that departure's live seat map, score the open seats inside your own cabin, and mark paid seats as paid. 2LNR can then keep watching the map for a better seat, which is the part a static 3U cabin diagram was never able to do.

**Where does this 3U fleet information come from?**

From the schedules 2LNR collects continuously and uses to build its own route map: every aircraft listed here is one 3U has filed against a nonstop route it operates, and the counts are the routes in that data. It is a picture of what is scheduled, not an aircraft register, so a type 3U owns but is not currently scheduling will not appear. Route lengths are great-circle distances between the two airports rather than flown track miles.

**What is the longest route Sichuan Airlines flies?**

Of the routes in 2LNR's schedule data, the longest 3U operates on its own metal is Los Angeles (LAX) to Chengdu (TFU), about 7,190 miles great-circle, flown on the Airbus A350-900. That is the distance between the two airports rather than the track the flight actually takes, and it is the routing rather than the aircraft that decides it: 3U schedules more than one type on many of its routes.
