On Thursday, Delta began its first service on its new Airbus A220-100 aircraft with flights between New York's LaGuardia Airport and each Dallas/Fort Worth International Airport and Boston. Delta has configured the aircraft with 12 First Class seats, 15 Delta Comfort Plus seats and 82 Main Cabin seats, and seating is wider than Delta's other narrowbody aircraft. Other routes slated for the aircraft this year include:
- March: Detroit to DFW
- April: LaGuardia to Houston Bush Airport
- May: Salt Lake City to DFW
- June: Minneapolis/St. Paul to DFW
- July: Houston Bush to Salt Lake City
- July: Houston Bush to Detroit, with continuing service to Minneapolis/St. Paul

Delta has a total order with Airbus for 40 A220-100s and 50 of the larger A220-300s to come into its fleet through the end of 2023, part of Delta's plans to replace 20 percent of its older aircraft over the next few years.
