Sichuan Airlines seat maps: which aircraft 3U actually flies

Sichuan Airlines (3U) operates 8 distinct aircraft types across 136 airports in 2LNR's schedule data, including Airbus A320, Airbus A320neo, and Airbus A321. On a fleet this varied, one seat number means different things on different departures of the same route, because the cabin you get depends on which airframe is assigned.

Sichuan Airlines fleet as flown

Aircraft types 3U currently schedules on its own metal. Regional flying under the 3U brand counts as 3U metal; flights 3U markets but another airline operates don't.

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, because that is what was filed; 2LNR doesn't guess the airframe.

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

Add the flight and open it. On Pro, 2LNR reads the seat map for that 3U flight and date, scores the open seats inside your own cabin and marks paid seats as paid. The map is read when you ask, not stored, so an aircraft swap shows up as a different map instead of a wrong one.

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.

2LNR doesn't publish stored cabin drawings or per-seat comfort ratings for 3U aircraft. To browse a layout on an aircraft you haven't booked, use a maintained diagram library such as AeroLOPA.

Frequently asked questions about Sichuan Airlines (3U) aircraft

What aircraft does Sichuan Airlines fly?
Eight aircraft types appear on Sichuan Airlines' own metal in 2LNR's schedule data, reaching 136 airports, including Airbus A320, Airbus A320neo, and Airbus A321. 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.
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 Chengdu (TFU) to Los Angeles (LAX), 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.
