JSX seat maps: which aircraft XE actually flies

In 2LNR's schedule data, JSX (XE) flies 3 aircraft types across 27 airports: Embraer ERJ-145, Embraer ERJ-135, and ATR 42. 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 XE flies it on, with the longest of them and the configuration on file where there is one.

The JSX fleet, as actually flown

Aircraft types XE currently schedules on its own metal, each with the nonstop routes it operates, how far those routes run and the cabin configuration XE records for it. Regional flying under the XE brand counts as XE metal; flights XE 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: that's 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 XE 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 XE flight and date you're looking at, scores the open seats inside your own cabin and marks paid seats as paid. It's 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.

If you want a cabin diagram instead

2LNR doesn't publish stored cabin drawings or per-seat comfort ratings for XE aircraft, and this page won't pretend otherwise. For browsing a layout on an aircraft you haven't booked, a maintained diagram library such as AeroLOPA is the right tool.

Frequently asked questions about JSX (XE) aircraft

What aircraft does JSX fly?
Three aircraft types appear on JSX's own metal in 2LNR's schedule data, reaching 27 airports, including Embraer ERJ-145, Embraer ERJ-135, and ATR 42. 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 XE brand is counted as XE metal; flights XE markets but another airline operates are not.
Does 2LNR publish XE seat maps by aircraft type?
Not as static diagrams. 2LNR reads the LIVE seat map for a specific XE 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 XE 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 XE cabin diagram was never able to do.
Where does this XE fleet information come from?
From the schedules 2LNR collects continuously and uses to build its own route map: every aircraft listed here is one XE 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 XE 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 JSX flies?
Of the routes in 2LNR's schedule data, the longest XE operates on its own metal is Dallas (DAL) to Burbank (BUR), about 1,240 miles great-circle, flown on the Embraer ERJ-145. 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: XE schedules more than one type on many of its routes.
