Columbus is served by John Glenn Columbus International Airport (CMH), the main airport for Ohio's capital and a key mid-sized hub. It offers a well-rounded domestic network with strong connectivity from major airline hubs and popular leisure destinations, supported by a mix of network, low-cost, and ultra-low-cost carriers.
The airport's most vital routes are flights from key domestic hubs, including Atlanta (ATL), Charlotte (CLT), Chicago (ORD), Dallas/Fort Worth (DFW), and Denver (DEN) to Columbus. It also offers direct flights from many popular leisure and business cities like Orlando (MCO), Fort Lauderdale (FLL), Las Vegas (LAS), New York (LGA, JFK), and Los Angeles (LAX).
Columbus is a focus city for Southwest Airlines and is served by all major U.S. carriers: American Airlines, Delta Air Lines, and United Airlines flying into CMH. Ultra-low-cost carriers Spirit Airlines and Frontier Airlines have a significant presence, driving down fares on many leisure routes into Columbus. This diverse mix creates good competition for arriving passengers.
To secure cheap flights to Columbus, book domestic flights 3-6 weeks in advance. For leisure arrivals from destinations served by Spirit or Frontier, book 2-3 months ahead for the lowest base fares into CMH, but carefully factor in their fees. Use flight comparison tools and set price alerts. Flying on weekdays (Tuesday-Thursday) is typically cheaper. Columbus often has competitive fares from Florida, the Northeast, and major hubs. For international travel to Columbus, connecting through a hub like Atlanta (ATL), Chicago (ORD), or New York (JFK) is standard. Southwest's presence often provides excellent value into Columbus, especially with free checked bags.
