Delta Air Lines is a major operator of aircraft from the Airbus A220 family. Formerly known as the Bombardier CSeries, this popular family of twinjet narrowbodies consists of two passenger-carrying variants, the smaller A220-100 and the larger A220-100, and such is Delta’s love of the type that it flies both models.
In this article, we will dive deeper into the data to detail the Delta Air Lines Airbus A220 fleet, by examining the number of units of each variant that it flies, any outstanding orders, and their respective seating configurations. Then, using data from Cirium, an aviation analytics company, we will analyze the top routes.
Delta’s A220 Fleet In A Nutshell
According to present fleet data made available by ch-aviation, 
Delta Air Lines currently has a grand total of 80 jets from the Airbus A220 series at its disposal. There is a relatively even split between the two variants, but the A220-100 comes out on top numerically, with 45 examples present. These jets are 5.9 years old on average, compared to 2.7 for its 35 A220-300s. Per aeroLOPA, both models have two-class seating configurations.
The smaller A220-100 can seat 109 passengers, with this figure split between 12 in domestic first class and 97 in economy (of which 15 have extra legroom). Meanwhile, the larger A220-300’s 130-seat capacity has space for 12 domestic first class seats and 118 in economy, with 30 seats in the latter cabin featuring extra legroom. Delta has 65 more A220-300s on order, with Kristen Bojko, its Vice President of Fleet, saying in July 2023 that:
“The A220-300 offers efficient performance and flexibility. The continuing expansion of Delta’s A220 family is an integral investment in the future of sustainable aviation.”
Top A220-100 Routes
This November, scheduling data made available by Cirium, an aviation analytics company, shows that Delta Air Lines has scheduled a grand total of 4,542 flights with the Airbus A220-100. These services will offer 495,078 seats and 450,351,921 available seat miles, and range from 129 to 1,770 miles.
Delta Air Lines’ top route with the A220-100 this month is comfortably the 1,389-mile (2,235.4 km) corridor between New York LaGuardia Airport (LGA) and Dallas/Fort Worth International (DFW). This November, it has scheduled 130 flights each way on this route with the A220-100, with between two and five a day.
Meanwhile, the only other route that Delta’s A220-100s will serve more than three times a day on average this month originates at Salt Lake City International Airport (SLC). Its destination is John Wayne Airport (SNA) in Santa Ana, California, and these aircraft will ply the 588-mile (946.3 km) corridor 92 times each way this month. Depending on the exact date, the carrier has penciled in either two, three, or four rotations with the type.
Top A220-300 Routes
Moving onto the larger Airbus A220-300, Delta Air Lines has scheduled 3,412 flights with this particular model of the popular narrowbody twinjet series in November of 2025. Collectively speaking, these services will offer grand totals of 443,560 seats and 510,375,190 available seat miles, with their lengths ranging from 185 to 2,306 miles. The shortest links LaGuardia with Boston, while the longest connects Seattle to Washington DC.
Delta Air Lines’ top route with the Airbus A220-300 by frequency this month also serves Boston Logan International Airport (BOS), with the other end of this corridor being Raleigh/Durham (RDU) in North Carolina. In November of 2025, the carrier has penciled in 126 A220-300 flights each way with the A220-300 on this 612-mile (984.9 km) route, equating to just over four a day on average. The exact daily frequencies range between two and five.
Delta has two other A220-300 routes with more than three flights a day on average this month, with the first linking LaGuardia with Houston (IAH). This November, 105 Delta flights will operate with the type on this 1,416-mile (2,278.8 km) route, which is also the case for the outbound leg on the 733-mile (1,179.7 km) corridor from Chicago O’Hare (ORD) to LaGuardia, although the return leg of this route ‘only’ has 104 A220-300 flights penciled in.
