Southwest Airlines Adjusts Lambert Airport Flight Schedule: What Travelers Need to Know

Southwest Airlines has announced a small but important change to its flight schedule at St. Louis Lambert International Airport (STL) for the third quarter of 2025. The airline is cutting about 2% of its flights at Lambert airport, focusing mostly on routes to the West Coast. At the same time, Southwest is adding or expanding some flights to the East Coast. This move is part of a larger plan by Southwest Airlines to reduce domestic flights across the United States 🇺🇸 in the second half of 2025. The main reasons are weaker demand for travel and ongoing uncertainty in the economy.

This update matters to many people—travelers, airport workers, local businesses, and anyone who relies on air travel in and out of St. Louis. Let’s break down what’s happening, why it’s happening, and what it means for you.

Why Southwest Airlines Is Cutting Flights at Lambert Airport

Southwest Airlines is the largest airline at Lambert airport. For years, it has offered more flights and destinations from St. Louis than any other carrier. But in July 2025, Southwest decided to trim its flight schedule at Lambert by about 2%. Most of these cuts affect flights heading to the West Coast, such as California and other western states. However, some flights to the East Coast are being added or expanded, which helps balance out the reduction.

The main reason for this change is that fewer people are booking flights within the United States 🇺🇸 right now. According to Southwest Airlines CEO Bob Jordan, the airline is making these changes because of “current market conditions.” In simple terms, people are not flying as much as they used to, especially for trips within the country. This is partly because of higher prices, inflation, and people being more careful with their money.

Southwest is not alone in making these changes. Other big airlines, like United Airlines and Delta Air Lines, have also announced they are cutting some domestic flights for the rest of 2025. This shows that the whole airline industry is facing similar problems.

How Big Is the Change at Lambert Airport?

The 2% cut in flights at Lambert airport may sound small, but it can still affect travelers. Here’s what you need to know:

• Most of the cuts are on West Coast routes. If you’re planning to fly from St. Louis to cities like Los Angeles, San Francisco, or Seattle, you might find fewer nonstop options.
• Some East Coast flights are being added or expanded. This means there could be more choices for travelers heading to places like New York, Washington, D.C., or Boston.
• Southwest remains the largest airline at Lambert. Even with these cuts, Southwest still offers more flights from STL than any other airline.

The airport director at Lambert has said there’s no major concern about the slight reduction. The airport continues to see strong service levels, and Southwest is still the dominant carrier.

What Does This Mean for Travelers?

If you’re planning to fly with Southwest Airlines from Lambert airport, here’s how the changes might affect you:

• Fewer nonstop flights to the West Coast. You may have to connect through another city or choose a different airline if your preferred nonstop route is no longer available.
• Possible higher ticket prices. When there are fewer seats available, prices can go up, especially during busy travel times or for popular destinations.
• More options to the East Coast. If you’re heading east, you might find more flights or better schedules.
• Need to book early and check for changes. Because airlines are adjusting their schedules, it’s smart to book your tickets early and keep an eye on your flight status. If demand stays low, more changes could happen.

Southwest Airlines is also making some other changes that travelers should know about:

• Assigned and extra-legroom seats will be available starting May 1, 2025.
• Checked bag fees will start for tickets booked after May 27, 2025. This is a big change, as Southwest has long been known for allowing two free checked bags.
• Reserved seating will begin in early 2026.

If your flight is canceled or rescheduled, Southwest usually offers to rebook you on another flight, give you travel credits, or provide a refund. It’s important to check your reservation often and contact Southwest customer service if you have questions.

Why Are Airlines Cutting Domestic Flights?

The airline industry is facing a tough time in 2025. Southwest Airlines reported a net loss of $149 million in the first quarter of the year. While this is better than last year, it still shows the airline is under financial pressure. The main reasons for the cuts include:

• Weaker demand for domestic travel. Fewer people are flying within the United States 🇺🇸, especially for leisure trips.
• Higher costs. Airlines are paying more for things like fuel, labor, and airport fees.
• Economic uncertainty. Many travelers are worried about inflation and the overall economy, so they are spending less on travel.
• Industry-wide trend. Other airlines, like United and Delta, are also cutting flights to avoid having too many empty seats.

Aviation experts say these cuts are a smart way for airlines to avoid losing money. By flying fewer planes on routes with less demand, airlines can keep their planes fuller and avoid wasting money on empty seats.

What’s the History of Southwest Airlines at Lambert Airport?

Southwest Airlines has been the top airline at Lambert airport since the early 2010s. This happened after American Airlines closed its hub in St. Louis in 2010. Since then, Southwest has added more flights and destinations, making it the main choice for many travelers in the region.

Over the years, Southwest has often increased its presence at Lambert, adding new cities and more frequent flights. That’s why this 2% reduction is seen as a small adjustment rather than a big change. The airline is still committed to serving St. Louis and remains the largest carrier at the airport.

How Will This Affect Different Groups?

Travelers:
People flying from St. Louis may find it harder to get nonstop flights to the West Coast. This could mean longer travel times, more connections, and possibly higher prices. On the other hand, travelers heading to the East Coast might see more options.

Airport Workers and Local Businesses:
A small reduction in flights is unlikely to cause major job losses or hurt local businesses at the airport. Since Southwest is only cutting 2% of its flights, most workers and businesses will not notice a big difference.

Southwest Airlines:
The airline is making these changes to stay financially healthy. By cutting flights where demand is low and adding flights where demand is higher, Southwest hopes to keep its planes full and its business strong.

Other Airlines:
With Southwest cutting some flights, other airlines might see a chance to add new routes or increase their own flights from Lambert airport. This could lead to more competition in the future.

What Should You Do If Your Flight Is Affected?

If you have already booked a flight with Southwest Airlines from Lambert airport, here’s what you should do:

1. Check your flight status regularly. Airlines sometimes change schedules, especially when demand is uncertain.
2. If your flight is canceled or changed, Southwest will usually offer to rebook you, give you a travel credit, or refund your ticket.
3. Contact Southwest customer service for help. You can call 1-800-I-FLY-SWA (1-800-435-9792) or visit southwest.com.
4. For airport information, visit flystl.com or call (314) 426-8000.

It’s also a good idea to book your tickets early, especially if you’re traveling during busy times or to popular destinations. With fewer flights, seats may sell out faster.

What Are the New Policies at Southwest Airlines?

Southwest Airlines is making some big changes to its policies in 2025 and 2026:

• Assigned and extra-legroom seats: Starting May 1, 2025, you can pay extra for a seat with more space or a specific seat assignment.
• Checked bag fees: For tickets booked after May 27, 2025, Southwest will start charging for checked bags. This is a major change, as the airline has always allowed two free checked bags.
• Reserved seating: In early 2026, Southwest will introduce reserved seating, letting you pick your seat ahead of time.

These changes are designed to help Southwest earn more money and keep up with other airlines. However, they may also mean higher costs for travelers, especially those who check bags or want extra space.

How Does This Fit Into the Bigger Picture?

The airline industry in the United States 🇺🇸 is going through a period of change. Domestic travel demand is down, while international travel is still strong. Airlines are adjusting their schedules to match what travelers want and to avoid flying empty planes.

Southwest Airlines is being careful. The company has even withdrawn its financial forecasts for 2025 and 2026, meaning it’s not making any promises about how much money it will make in the future. This shows that Southwest is being cautious and wants to be ready for whatever happens next.

Other airlines are doing the same thing. United Airlines and Delta Air Lines have both announced cuts to their domestic schedules for the second half of 2025. This is an industry-wide trend, not just something happening at Southwest.

What Do the Experts Say?

Aviation analysts believe that Southwest’s decision to cut flights is a smart move. They say the airline is responding to higher costs, inflation, and travelers who are more careful with their money. Middle-class travelers, in particular, are watching their budgets and may be less likely to fly for leisure.

Experts also note that airlines are focusing more on international routes, where demand is still strong. By cutting some domestic flights, airlines can move planes to routes that are more profitable.

According to analysis by VisaVerge.com, these changes are likely to continue as long as the economy remains uncertain. Airlines will keep adjusting their schedules to match demand and avoid losing money.

What’s Next for Southwest Airlines and Lambert Airport?

Travelers should expect more changes in the future. If demand stays low or the economy gets worse, Southwest and other airlines may cut more flights. On the other hand, if more people start flying again, airlines could add flights back.

Southwest’s new seating and baggage policies will also be closely watched. Travelers and industry experts will want to see how these changes affect customer satisfaction and the airline’s profits.

For now, the best advice is to stay informed. Check your flight status, book early, and be ready for possible changes.
