American Airlines Embraer ERJ-145 seat maps and routes

The Embraer ERJ-145 covers 172 nonstop routes and 72 airports for American Airlines (AA) in 2LNR's schedule data, Charlotte to Charlottesville, Tallahassee to Charlotte, and Gainesville to Charlotte among them. Every route below links to that city pair, so you can find a departure on this aircraft rather than guessing. What is not here is a static cabin diagram: 2LNR reads the live seat map for a specific flight and date instead.

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 AA 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 is the right tool.

What is on this page

Every nonstop route American Airlines currently schedules the Embraer ERJ-145 on, taken from the flight schedules 2LNR collects continuously. The aircraft is a Embraer ERJ-145, a regional jet. AA files it as ER4 in its schedules; those spellings are treated as one aircraft here rather than as separate types.

The longest of those routes is Charlotte (CLT) to Shreveport (SHV), about 760 miles. The median route runs about 340 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 AA flies the Embraer ERJ-145

Frequently asked questions about the AA Embraer ERJ-145

Where does American Airlines fly the Embraer ERJ-145?
On 172 nonstop routes touching 72 airports in 2LNR's schedule data, Charlotte to Charlottesville, Tallahassee to Charlotte, and Gainesville to Charlotte 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 AA currently has filed rather than a permanent assignment.
Can I see the Embraer ERJ-145 seat map for a AA 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 Embraer ERJ-145 diagram, which cannot tell you whether 12A is free or whether the aircraft was swapped.
Is the Embraer ERJ-145 the only aircraft on these AA routes?
No. A route appears here when AA has scheduled the Embraer ERJ-145 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 Embraer ERJ-145?
Not as a published library of per-seat comfort ratings for the Embraer ERJ-145, and this page will not invent them. What 2LNR scores is the seats actually open in your cabin on your AA flight, so the answer is a seat you can select rather than a general opinion about a row. For browsing a Embraer ERJ-145 cabin layout on an aircraft you have not booked, a maintained diagram library such as AeroLOPA remains the better tool.
How far does the Embraer ERJ-145 fly for AA?
The longest of the 172 routes AA schedules it on is Charlotte (CLT) to Shreveport (SHV), about 760 miles measured great-circle between the two airports rather than as flown track miles. The median route on this aircraft runs about 340 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.
