A brief overview of air transport in St. Louis, Missouri

St. Louis, the second-largest city in Missouri State, has two passenger airports. The primary passenger facility is St. Louis Lambert International Airport (STL), whereas the second one is MidAmerica St. Louis Airport (BLV).

As the largest and busiest airport in the state, STL serves as a primary gateway to the West. It accommodates nonstop airline service to airports throughout the US and features international routes to Mexico, Canada, the Caribbean, and Europe. Around 15 airlines operate passenger flights at STL Airport, and Spirit Airlines is one of them.

Spirit Airlines St. Louis operation: Background

Not even two years have passed since Spirit added St. Louis to its route map. The discount airline entered the St. Louis market for the first time on May 27, 2021, by launching flights to four US cities. The carrier inaugurated St. Louis operations with daily services to Los Angeles (LAX), Fort Lauderdale (FLL), Las Vegas (LAS), and Orlando (MCO). A few days later, i.e., on June 10, 2021, Spirit Airlines added Pensacola to its growing St. Louis portfolio of services.

Driven by the aim to grow in St. Louis, Spirit soon almost doubled down its destination count from STL. On top of its core markets like Orlando or Fort Lauderdale, the carrier stretched its St. Louis network to a number of leisure destinations for the winter season.


On November 17, 2021, the discount carrier launched daily services from St. Louis to Fort Myers, Phoenix, and Tampa. Spirit’s low-cost, nonstop flights to these vacation destinations opened doors for Gateway City residents to enjoy a quick getaway.

In December, Spirit Airlines added Cancun as its first international destination from St. Louis to keep up with the route expansion. The no-frills flyer inaugurated its first St. Louis international service to Cancun on December 22, 2021. Cancun, the Mexico City situated on the Yucatan Peninsula, became Spirit’s latest nonstop destination from STL. The ultra-low-cost carrier departed STL daily at 6:30 am for Cancun and returned back at 2:03 pm.

Overall, Spirit Airlines has served eight nonstop destinations from St. Louis across its nearly 2-year presence at STL. Let’s break down the routes according to their launch dates.

From St. Louis to:

  • Spirit’s three biggest cities (Fort Lauderdale, Las Vegas, and Orlando); launch date- May 27, 2021
  • Los Angeles (LAX); launch date-May 27, 2021
  • Pensacola (PNS); launch date-June 10, 2021
  • Three fun destinations (Fort Myers, Phoenix, and Tampa); launch date November 17, 2021
  • Cancun (first international destination from STL); launch date December 22, 2021

Spirit Airlines St. Louis: Current routes

Currently, Spirit Airlines doesn’t serve all eight aforementioned destinations from St. Louis. In January 2023, the ULCC dropped 37 routes from its network as part of its scheduled adjustments. The Miami-based carrier cut off scheduled flights on 37 routes citing supply chain woes on aircraft deliveries and engine manufacturing/overhaul. As a result, it also scrapped some St. Louis routes from the schedule, like FLL-STL, PHX-STL, RSW-STL, etc.

So, where does Spirit Airlines fly direct from STL at present?

Spirit Airlines currently flies directly from STL to Orlando International Airport and Harry Reid International Airport.

The ultra-low-fare carrier offers nonstop flights on STL-MCO and STL-LAS routes. Let’s dig into details about these routes.

  • Spirit Airlines St. Louis to Orlando flights

Miramar, Florida-headquartered Spirit Airlines maintains one of its largest operating bases at Orlando Airport. It offers regularly scheduled services between Orlando and St. Louis, linking people and businesses in ‘O-Town’ with the Gateway City. St. Louis customers headed to/from Orlando can enjoy affordable travel and greater choice offered by Spirit Airlines’ ultra-low-cost flights.

Both NK 1132 and NK1130 serve the STL-MCO route, flying nonstop for nearly 2 hours and 30 minutes. Spirit Airlines deploys Airbus A319 to perform flight NK1132 and Airbus A320 for NK1130. The departure and arrival timing may vary each day.

For e.g., Spirit Airlines Flight NK1130 will depart STL at 4:35 pm and arrive in MCO at 7:59 pm on April 27. However, the flight departure and arrival times are set at 3:00 pm and 6:24 pm the next day.

The return flight NK1131 traveling from Orlando to St. Louis also has different departure and arrival timing each day.

Since Orlando is Spirit’s big city, passengers flying nonstop from STL can easily connect through Orlando to cities throughout the US. For example, Spirit passengers traveling from St. Louis can use Orlando as a connection to other US airports like Los Angeles, Dallas, Atlanta, etc.

Spirit Airlines uses both A and B terminals among three passenger terminals at ORD. ORD terminal A lies on the northern side of the main terminal and has gates 1-29 and 100-129. Similarly, Terminal B (the southern half of the main building) has gates 30-59 and 70-99.
