Q400 vs ATR 72-600: which regional turboprop is right for you?

The Dash 8 Q400 and ATR 72-600 are the two turboprops most operators shortlist. Here's how they compare on speed, economics, capacity and field performance, and which fits which mission.

For operators building or renewing a regional turboprop fleet, two aircraft dominate the shortlist: the Bombardier Dash 8 Q400 and the ATR 72-600. Both are modern, efficient 70-plus-seat turboprops with a strong global support base, and operators often ask us to settle the question for them. The honest answer is that neither is universally "better", they are optimised for different missions. This guide breaks down where each one wins.

Q400 vs ATR 72-600 at a glance

Indicative figures for comparison; exact performance varies by build standard, configuration and payload. Specification for any available airframe is provided on request.

Speed: the Q400's clearest advantage

The Q400 cruises around 360 knots, roughly 80 knots faster than the ATR 72-600. On a 300 nm sector that is a meaningful block-time saving, enough, on the right network, to squeeze an extra rotation into the day or to hold a jet-competitive schedule without a jet's fuel burn. If your routes are time-sensitive, feed tight banks at a hub, or compete directly with regional jets, the Q400's speed is hard to ignore.

Fuel burn and trip cost: the ATR's home ground

The ATR 72-600 is built around economy. It is lighter, flies slower, and burns notably less fuel per trip than the Q400, which gives it the lowest seat-mile and trip costs in the class on shorter sectors. On thin routes where you cannot reliably fill 86 seats, that lower trip cost is decisive: you are not paying to move an aircraft, or seats, you do not need. For operators whose networks are short and demand is modest, the ATR is usually the lower-risk economic choice.

Capacity and range

The Q400 carries more, up to 90 seats against roughly 78 for the ATR, and flies farther, which matters if you need to upgauge busy routes or reach destinations the ATR cannot comfortably serve. The ATR's range is ample for the short sectors it is designed around, but the Q400 gives you more headroom to grow frequency into capacity, or to operate longer regional legs, without changing fleet type.

Field performance and operating environment

The ATR 72-600 needs less runway and performs well in hot-and-high conditions and at short or less-developed airports, which opens up airfields the Q400 may not serve as easily. If your network includes short strips, high-elevation airports or demanding climates, weigh field performance carefully, it can decide the matter regardless of economics.

Maintenance, support and residuals

Both types share Pratt & Whitney Canada turboprop lineage and enjoy mature, global support networks and parts availability, so neither is an orphan. The practical differences show up in your specific situation: existing fleet commonality, your approved maintenance organisation's experience on type, spares pooling and the condition of the individual airframe you are buying. On the used market, those airframe-level factors, engine and LLP status, records quality, modification state, usually matter more to total cost than the badge on the tail. This is exactly where a disciplined pre-purchase process and, on entry into service, a bridging check protect your investment.

The verdict

In practice the "right" answer falls out of your network, not a spec sheet. Share your routes, frequencies and growth plans with us and we will model both against your actual operation, objectively, and help you acquire the right airframe at the right price. We can source and support both types.
