DENVER, COLARADO — The American ultra-low-cost carrier Frontier Airlines is expanding its significant footprint at Hartsfield-Jackson Atlanta International Airport (ATL), unveiling five fresh routes that will include international destinations such as the Dominican Republic and Guatemala.


From May 11, Frontier initiated services from ATL to Ontario International Airport (ONT) in California; Santo Domingo Las Americas International Airport (SDQ) in the Dominican Republic; and San Diego International Airport (SAN). The ONT and SAN routes will have daily flights, while the SDQ route will run twice a week.

Starting May 12, Frontier is rolling out a twice-weekly service connecting ATL with Guatemala City's La Aurora International Airport (GUA), and a thrice-weekly flight connecting ATL with Salt Lake City International Airport (SLC).

Delta Air Lines, headquartered in Atlanta, held a dominant market share of more than 75% at the airport as of January. During the same month, Frontier accounted for 3.04% of ATL's passenger capacity. Apart from Delta, only Southwest Airlines (7.38%) and Spirit Airlines (3.16%) boasted a larger share. Frontier, which exclusively operates Airbus A320-family aircraft, established a crew base at ATL in 2021, employing around 400 personnel.

All of Frontier's new routes, which are also serviced by Delta, augment the Denver-based airline's list of nonstop ATL destinations to 38.

Frontier's Senior Vice President for Commercial, Daniel Shurz, expressed the airline's enthusiasm for the growth in a statement. "Atlanta is one of our fastest-growing markets and serves as a large international gateway for Frontier,” he said. "Connecting Atlanta to Guatemala City and Santo Domingo, while continuing to expand our domestic options, is all part of a significant growth push at ATL that underscores our robust commitment to Atlanta.”
