Greenville Is Growing. Can GSP Airport Keep Up?

Greenville keeps growing, more people are moving to the Upstate, and businesses continue bringing new jobs to the area. With all that growth, it would seem reasonable to expect more nonstop flights from Greenville-Spartanburg International Airport. After all, more people should mean more travelers, which should mean more airlines wanting to serve the area. Right?

Unfortunately, it's not quite that simple. GSP is making progress, with additional Breeze Airways routes, airport improvements, and long-term expansion plans. But attracting airlines is only half the battle. Convincing passengers to actually use those flights, especially when Charlotte and Atlanta are relatively close, presents another challenge.

Trudy Carson, Passenger Development Manager at GSP, explains what goes into bringing new flights to Greenville, why some routes disappear, and what the airport needs to keep growing alongside the Upstate.

Can GSP Airport Keep Up With Greenville's Growth?

The opportunity for GSP Airport is pretty obvious. Greenville is attracting more residents, businesses, and visitors, which creates more potential passengers. But airlines aren't adding flights simply because a region is growing. They need routes that make financial sense, available aircraft, and enough travelers willing to book those flights. That's where the process becomes considerably more complicated than most people realize.

Why getting more nonstop flights isn't so simple

Carson's job involves identifying where people want to travel and convincing airlines that those destinations are worth serving. But demand alone isn't enough. Airlines have limited aircraft, and every plane assigned to Greenville is one that could potentially make more money somewhere else. They also have to consider scheduling, connections, and how a new route fits into their existing network. A flight that looks attractive to travelers might not work financially or operationally for the airline.

The other problem is that people don't always use the flights they ask for. Someone might want nonstop service to Columbus, Ohio, but refuse to book it because the route is operated by Breeze instead of Delta. That might seem like a minor detail, but it matters when airlines are deciding whether a route deserves to stay. Getting a flight is one thing. Keeping it requires enough people to actually purchase tickets.

More Breeze Airways flights are on the way

Breeze Airways has become one of the more active airlines at GSP, particularly when it comes to introducing nonstop leisure destinations. New service to West Palm Beach is expected to begin around December 18, while seasonal flights to Columbus, Cincinnati, Pittsburgh, and Los Angeles are scheduled to return around April or May 2027. The Los Angeles route has been particularly popular, offering travelers a nonstop option to the West Coast that wasn't previously available in the same way.

There is a catch, however. Breeze and Avelo generally operate many of their routes only a few days per week, often with departures on Thursdays or Fridays and returns on Sundays or Mondays. That's convenient for vacations, but not necessarily for business travelers who need more flexibility. Seasonal routes also allow airlines to test demand without committing to year-round service. If passengers don't support those flights, there's no guarantee they'll return the following season.

Why Charlotte and Atlanta are still a problem for GSP

One of GSP's biggest challenges is something the airline industry calls leakage. That's when travelers who live near Greenville choose to fly out of Charlotte or Atlanta instead. Those larger airports offer more destinations, but Carson points out that travelers shouldn't automatically assume they're getting a better deal by driving there. In some cases, a flight originating at GSP and connecting through Charlotte can actually cost less than starting the trip in Charlotte.

There's also the convenience factor. GSP offers a much less stressful airport experience, with efficient security screening, easier access, and none of the long drives associated with reaching larger airports. For travelers who have spent years automatically booking through Charlotte or Atlanta, it's worth reconsidering whether that drive is necessary. The time spent on the road, parking expenses, and general hassle are all part of the actual cost of a trip.

More importantly, when Upstate residents consistently choose other airports, they make it harder for GSP to demonstrate the passenger demand needed to attract additional flights.

What happens when an airline route fails?

Avelo previously operated a flight between GSP and Manchester, New Hampshire, but the route didn't perform well enough to continue. Carson believes the problem may have involved too many available seats for the level of demand. A smaller aircraft might make the route more practical, but convincing another airline to try a destination that has already struggled isn't easy.

That's why maintaining existing service is such a priority. When airport officials approach an airline about adding a destination, the performance of previous routes becomes part of the discussion. Airlines need evidence that a market can support their investment. The Manchester situation doesn't necessarily mean Greenville lacks travelers interested in New Hampshire. It means the particular service offered didn't generate enough business to continue.

For GSP, the challenge is finding the right airline, aircraft size, and schedule for each destination.

International passenger service is part of the long-term plan

Greenville has substantial business connections with international destinations, including Munich and manufacturing centers in Mexico. Carson discussed how GSP works with airlines to improve connections through larger airports, particularly for business travelers. United's Houston service, for example, has been coordinated to provide better connections to Querétaro, Mexico, an important destination for companies with manufacturing operations there.

But nonstop international passenger service presents a different challenge. GSP currently handles international cargo operations, but it doesn't have the federal inspection facilities needed to process international passenger arrivals. Carson estimates that developing those capabilities could take approximately another decade.

Before certain expansion projects can move forward, the airport's existing FAA control tower needs to be relocated. Work on a new, taller, more advanced tower is expected to begin in 2027. Until that happens, the current tower limits what the airport can do with its available space.

GSP is already making improvements

While international passenger service remains a long-term goal, several airport improvements are happening much sooner. GSP now has three parking garages, with solar panels being installed to help generate electricity and reduce dependence on outside power sources. That's particularly useful when storms or other disruptions affect electrical service.

The airport is also nearing completion of its runway reconstruction project, with work expected to finish by December. Much of the remaining construction is taking place at night to minimize disruptions, although the project has already required temporary closures and adjustments to airline schedules.

Inside the terminal, additional improvements are being considered. The popular Escape Lounge may eventually expand, while changes to airport concessions could bring new vendors and retail options. GSP already benefits from substantial business travel, which helps support amenities that might otherwise seem unusual for an airport of its size.

There's also an outdoor garden accessible after security, along with a children's playground that opened approximately a year ago. Those are relatively small features, but they contribute to what makes GSP different from larger airports.

Greenville's growth is an advantage, but it isn't everything

Airlines absolutely pay attention to Greenville's growth. New residents create demand for visiting friends and relatives, tourism brings additional passengers, and certain types of job growth generate significant business travel. Carson regularly uses those developments when making the case for additional service, and GSP has even brought airline network planners to the Upstate to experience the area firsthand.

But not every new job creates the same demand for air travel. A manufacturing operation with employees regularly visiting facilities in other states or countries may generate more airline activity than a business whose employees rarely travel. Understanding those differences helps GSP make a stronger argument when approaching potential airline partners.

The airport also faces broader industry challenges, including fuel costs, airline competition, and the availability of aircraft. Still, Greenville's growing economy and expanding population put GSP in a favorable position. The question is whether that growth will translate into enough sustained passenger demand to support more service.

And that depends partly on the people living here.

Bottom Line

Greenville's growth gives GSP Airport a real opportunity to attract more airlines, expand its facilities, and improve connections to destinations throughout the country and eventually overseas. But population growth alone isn't going to make that happen.

Airlines need profitable routes, and they pay attention to whether passengers actually use the flights being offered. That's the part travelers sometimes overlook. It's difficult to complain about the lack of nonstop service while consistently choosing to fly from Charlotte or Atlanta instead.

GSP has new destinations coming, additional improvements underway, and longer-term expansion plans. Whether those opportunities lead to even more flights will depend on something relatively simple: people actually flying out of Greenville.
