Frontier Challenges Delta with Major Atlanta Expansion
Frontier Airlines is significantly expanding its presence at Hartsfield-Jackson Atlanta International Airport (ATL) with nine new routes launching between May and June 2025.
This expansion will increase the airline's departures by 40% year-over-year, making Atlanta one of Frontier's top three bases in the U.S. alongside Denver and Orlando.
Key Points
- The nine new routes include two international destinations: Aruba (AUA) and San Pedro Sula, Honduras (SAP)
- Domestic destinations include Oklahoma City (OKC), Kansas City (MCI), St. Louis (STL), Columbus (CMH), and Florida destinations Fort Myers (RSW), Jacksonville (JAX), and West Palm Beach (PBI)
- Routes will begin launching on May 22 with Oklahoma City, followed by Kansas City on May 23, Aruba on May 24, and the remaining routes in June
- By summer, Frontier will serve 52 destinations from Atlanta with approximately 363 weekly departures, up from about 250 during the same period in 2024
- Promotional fares for the new routes start at $29 one-way for travel between May 24 and August 18, 2025, with some blackout dates
- Frontier will compete directly with Delta Air Lines on all nine new routes
- The airline is now operating from newly-built gates on the E Concourse at ATL
- Frontier expects to employ more than 1,200 people at ATL this year, including pilots, flight attendants, and ground staff
What It Means
Frontier is strategically filling the void left by Southwest Airlines, which has cut about a third of its Atlanta destinations and crew this year.
With these additions, Frontier may soon surpass Southwest to become ATL's second-largest carrier after Delta.
This move positions Frontier as the primary low-cost alternative to Delta at the world's busiest airport, targeting primarily leisure travelers while Delta focuses on business passengers.
