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 9M flies it on, with the longest of them and the configuration on file where there is one. Updated October 21, 2026.

Regional flying under the 9M brand counts as 9M metal; flights 9M markets but another airline operates don't. ### De Havilland Canada Dash 8-100 Turboprop · Filed as DH1 **Nonstop routes**\ 40 **Airports served**\ 13 **Typical route**\ 220 mi Longest route: [Blanc-Sablon (YBX) to Montreal (YUL)](https://2lnr.com/routes/ybx-yul.md), about 860 miles. #### Routes it flies most - [Quebec City (YQB) to Montreal (YUL)](https://2lnr.com/routes/yqb-yul.md) - [Chevery (YHR) to St-Augustin (YIF)](https://2lnr.com/routes/yhr-yif.md) - [Le Golfe-du-Saint-Laurent (ZGS) to Chevery (YHR)](https://2lnr.com/routes/zgs-yhr.md) - [Sept-Iles (YZV) to Quebec City (YQB)](https://2lnr.com/routes/yzv-yqb.md) - [St-Augustin (YIF) to Blanc-Sablon (YBX)](https://2lnr.com/routes/yif-ybx.md) - [Sept-Iles (YZV) to Havre-Saint-Pierre (YGV)](https://2lnr.com/routes/yzv-ygv.md) [The other 34 routes on the 9M route map](https://2lnr.com/routes/airlines/9m.md) ### Beechcraft 1900 Turboprop · Filed as BEH **Nonstop routes**\ 34 **Airports served**\ 15 **Typical route**\ 150 mi Longest route: [Blanc-Sablon (YBX) to Sept-Iles (YZV)](https://2lnr.com/routes/ybx-yzv.md), about 400 miles. #### Routes it flies most - [Le Golfe-du-Saint-Laurent (ZGS) to Havre-Saint-Pierre (YGV)](https://2lnr.com/routes/zgs-ygv.md) - [Prince George (YXS) to Kelowna (YLW)](https://2lnr.com/routes/yxs-ylw.md) - [Port-Menier (YPN) to Sept-Iles (YZV)](https://2lnr.com/routes/ypn-yzv.md) - [Havre-Saint-Pierre (YGV) to Port-Menier (YPN)](https://2lnr.com/routes/ygv-ypn.md) - [Prince George (YXS) to Edmonton (YEG)](https://2lnr.com/routes/yxs-yeg.md) - [Sept-Iles (YZV) to Port-Menier (YPN)](https://2lnr.com/routes/yzv-ypn.md) [The other 28 routes on the 9M route map](https://2lnr.com/routes/airlines/9m.md) ### Fairchild Dornier 328 Turboprop · Filed as D38 **Nonstop routes**\ 4 **Airports served**\ 3 **Typical route**\ 330 mi Longest route: [Prince George (YXS) to Calgary (YYC)](https://2lnr.com/routes/yxs-yyc.md), about 410 miles. #### Routes it flies most - [Prince George (YXS) to Calgary (YYC)](https://2lnr.com/routes/yxs-yyc.md) - [Calgary (YYC) to Prince George (YXS)](https://2lnr.com/routes/yyc-yxs.md) - [Prince George (YXS) to Terrace (YXT)](https://2lnr.com/routes/yxs-yxt.md) - [Terrace (YXT) to Prince George (YXS)](https://2lnr.com/routes/yxt-yxs.md) 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 9M 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 9M 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](https://2lnr.com/lp/seat-monitoring.md). ### If you want a cabin diagram instead 2LNR doesn't publish stored cabin drawings or per-seat comfort ratings for 9M 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](https://www.aerolopa.com/) is the right tool. ## More on Central Mountain Air - [Where 9M flies: the Central Mountain Air route map](https://2lnr.com/routes/airlines/9m.md) - [Seat maps by airline and aircraft](https://2lnr.com/seatmaps.md) - [How to read an airline seat map](https://2lnr.com/guides/airline-seat-maps.md) - [What replaced SeatGuru](https://2lnr.com/compare/seatguru.md) ## Frequently asked questions about Central Mountain Air (9M) aircraft **What aircraft does Central Mountain Air fly?** Three aircraft types appear on Central Mountain Air's own metal in 2LNR's schedule data, reaching 21 airports, including De Havilland Canada Dash 8-100, Beechcraft 1900, and Fairchild Dornier 328. 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 9M brand is counted as 9M metal; flights 9M markets but another airline operates are not. **Does 2LNR publish 9M seat maps by aircraft type?** Not as static diagrams. 2LNR reads the LIVE seat map for a specific 9M 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 9M 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 9M cabin diagram was never able to do. **Where does this 9M fleet information come from?** From the schedules 2LNR collects continuously and uses to build its own route map: every aircraft listed here is one 9M 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 9M 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 Central Mountain Air flies?** Of the routes in 2LNR's schedule data, the longest 9M operates on its own metal is Blanc-Sablon (YBX) to Montreal (YUL), about 860 miles great-circle, flown on the De Havilland Canada Dash 8-100. 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: 9M schedules more than one type on many of its routes. ## See the seats on your 9M flight Free to start.
