An airline needs at least 25 nonstop routes on the De Havilland Canada Dash 8-400, on its own metal, and at least 3 aircraft types that clear the same bar to be listed, so a smaller De Havilland Canada Dash 8-400 operation can be missing.

## Frequently asked questions about the De Havilland Canada Dash 8-400

**Which airline flies the De Havilland Canada Dash 8-400 on the most routes?**

Of the airlines with a De Havilland Canada Dash 8-400 page here, WestJet schedules it on the most nonstop routes in 2LNR's schedule data: 106, reaching 27 airports. Air Canada is next with 99, then Qantas with 97. Schedules move with the seasons, so the order can change.

**Does the De Havilland Canada Dash 8-400 have the same cabins on every airline?**

No. Each airline fits its own cabins and seats, so the De Havilland Canada Dash 8-400 on WestJet and the De Havilland Canada Dash 8-400 on Air Canada can be quite different inside, and one airline can fly more than one layout.

**Can I see the De Havilland Canada Dash 8-400 seat map for my flight?**

Yes, on Pro, for the specific flight and date you're on. 2LNR reads that flight's De Havilland Canada Dash 8-400 seat map when you ask, scores the open seats inside your cabin and marks paid seats as paid.

## No cabin diagram here

2LNR doesn't publish stored seat diagrams for the De Havilland Canada Dash 8-400 or any other aircraft. On Pro it reads the live seat map for a specific flight and date, which is the version that survives an aircraft swap. For a drawing of a cabin you haven't booked, a maintained library such as [AeroLOPA](https://www.aerolopa.com/) is the right tool.
