The anticipated retirement of 50-seat regional jets from U.S. fleets is creating a market opportunity that could prompt ATR to change one of its aircraft’s longstanding features. The manufacturer has unveiled an ATR 72-600 concept featuring a forward passenger door compatible with jet bridges and a three-class cabin, aiming to meet the requirements of U.S. airlines seeking a higher standard of passenger service in a replacement for smaller CRJs.

According to Aviation Week, the concept was presented on September 23 at the Regional Airline Association Leaders Conference in Washington. It features 50 seats, a forward galley and sufficient storage for every passenger’s cabin bag. Developed in consultation with airlines, the proposal has yet to receive a formal programme launch. ATR first wants to establish whether there is sufficient market interest.

The most significant change concerns boarding arrangements. ATR passenger aircraft have long been associated with a rear passenger entrance and a forward baggage and cargo compartment between the flight deck and passenger cabin. The proposed version departs from that conventional layout, adapting the forward section for boarding via a jet bridge, with direct access to the premium cabin and its catering facilities. ATR identifies this entrance arrangement as a key feature of its proposed U.S. configuration.

For U.S. network airlines, a regional aircraft must fit into major hub operations while maintaining the product offered throughout a passenger’s journey. That includes jet-bridge boarding, premium seating options and adequate carry-on baggage space. ATR’s proposal therefore addresses both cabin design and boarding arrangements, bringing the passenger experience closer to that of the regional jets it hopes to replace.

The proposed layout comprises 10 seats in the highest class, 20 Economy Plus seats and 20 standard economy seats. Seat pitch would be approximately 40 inches in the forward cabin, 33 inches in Economy Plus and 30 inches in economy. ATR’s documentation identifies the forward seats as Business “Privilege”, while Aviation Week describes this section as first class, consistent with U.S. domestic terminology. The middle category is economy seating with additional legroom.

This approach already has an established precedent in the U.S. regional market. The CRJ550, operated under the United Express brand, was also introduced with 50 seats, including 10 in first class and 20 in Economy Plus. ATR aims to offer a similar arrangement in a turboprop, using the ATR 72’s interior space to create a more comfortable, lower-capacity cabin.

Carry-on baggage storage is another important element of the concept. According to Aviation Week, the layout provides space for 30 roller bags in overhead bins and another 24 in dedicated floor-mounted compartments. Baggage capacity would therefore exceed the number of passengers, reducing the need to hand over cabin bags during boarding. The proposed cabin also has an aisle approximately two inches wider and around one inch more headroom than the CRJ550.

The business opportunity stems from ageing CRJ200 and Embraer ERJ145 fleets, which have connected smaller U.S. communities to major hubs for decades. Their gradual retirement creates a need for replacements of a suitable size, particularly on routes where larger aircraft would struggle to support the desired number of daily departures. In its own analysis, ATR notes that the original manufacturers of these jets no longer offer a new-build replacement in the same category, while maintaining existing aircraft is becoming increasingly expensive.

ATR is also counting on the advantages of turboprop propulsion on shorter routes. According to the manufacturer, its aircraft can burn up to 45% less fuel than ageing 50-seat regional jets on missions typical of U.S. regional networks. Actual savings would depend on individual operations, but ATR presents lower fuel consumption as the economic foundation for a configuration with fewer seats and a greater share of passengers travelling in higher fare categories.

ATR chief commercial officer Alexis Vidal told Aviation Week that the manufacturer expects stronger demand around 2030. He considers that timeframe realistic from an industrial standpoint as well, allowing for the development and potential delivery of the proposed version. The concept would use the current ATR 72-600 platform, separately from longer-term plans for a next-generation aircraft.

A forward passenger door is not an entirely new idea within ATR’s offering: it already appears alongside a three-class layout in the manufacturer’s HighLine documentation. The Washington presentation marks a further step towards potential implementation, allowing ATR to gauge interest directly among U.S. operators. Bringing such a version to market would represent an important adaptation to a market where cabin amenities, baggage space and compatibility with airport infrastructure matter alongside operating costs. A programme launch will depend on whether airlines see the adapted ATR as a viable long-term replacement for their regional jets.
