The Airbus A220 has quietly become one of the most useful aircraft in the US market, and three very different airlines are leaning on it in three very different ways. Delta, JetBlue and Breeze Airways have all placed big orders, but the plane plays a distinct role at each.

Delta is the world's largest A220 operator, with 145 ordered — 45 of the smaller -100 and 100 of the larger -300. It was also the type's first US customer, back when it was still the Bombardier CSeries. For Delta, the A220 handles longer domestic sectors with modest demand: think Seattle to Washington DC rather than high-frequency short hops, which go to its ageing Boeing 717s. The smaller -100 is Delta's only A220 variant and the only one flown by a full-service US carrier, complete with a first class cabin. A quirk of Delta's pilot contracts also classifies the A220 as a small narrowbody, unlocking extra 76-seat regional jets. Crew bases include New York, Salt Lake City, Seattle and, most recently, Minneapolis.

JetBlue has ordered 100 A220-300s and is doubling down while deferring new A321neo deliveries until 2030. The type replaced its retired Embraer E190s and is now its second-largest fleet at 140 all-economy seats each. Typically based at Boston, New York JFK and Fort Lauderdale, the A220 mostly flies domestic routes, including markets where JetBlue faces stiff competition — Atlanta, Delta's fortress — though it does reach some Caribbean destinations.

Then there's Breeze, where the A220 is everything. The young carrier flew only a handful of Embraer E-jets before switching entirely; it now runs 66 A220-300s with 24 more coming, making it the world's third-largest operator of the type. Its point-to-point model links underserved cities to leisure spots on routes ranging from Orlando–Key West to Las Vegas–Windsor Locks. Running a single aircraft type keeps costs low, and Breeze is already posting occasional profits as it aims to become a genuine national competitor.

Why does this matter for travellers? If you're flying domestically in the eastern US, you have a good chance of ending up on an A220 — quieter, newer and generally more comfortable than the regional jets and older narrowbodies it replaces. Delta's versions include first class; JetBlue's offer extra legroom in its standard configuration; Breeze's low fares open up routes that bigger airlines ignore. And the A220's momentum is global — Air Asia ordered 150 of them in 2026, and the type has now passed 1,100 orders, outselling its direct rivals like the 737 MAX 7 and A319neo.

For now, the aircraft remains mostly an eastern-US sight across all three carriers, though Delta increasingly flies it in the west. As deliveries continue, expect to see a lot more of it.
