As the dust begins to settle following Spirit Airlines' bankruptcy and subsequent cessation of operations, the airport sector overall should be able to weather the storm with limited impact, analysts said.
"The impact on the [U.S.] airport sector will be negligible," said Doug Kilcommons, head of the KBRA public finance group.
Spirit's halting service after a failed $500 million bailout comes as the airport sector remains resilient during ongoing geopolitical tensions, with spreads compressing compared to other transportation sectors despite elevated fuel costs, Barclays strategists said.
"Some airports are more exposed to airlines currently under pressure, particularly medium- and small-sized airports in tourist markets," they said.
Some smaller regional airlines relied mostly on Spirit, like Arnold Palmer Regional Airport in Latrobe, Pa., and the Atlantic City International Airport, said a sellside source.
"Those airports are really going to [need to] figure something out," he said.
Other airports like Fort Lauderdale-Hollywood International Airport, Orlando International Airport, iand Louis Armstrong New Orleans International Airport, along with Newark Liberty International Airport and LaGuardia Airport will be affected to a lesser extent, Barclays strategists said.
"Spirit Airlines' cessation of operations will negatively impact [Fort Lauderdale's airport], given it represents over 30% of total annual enplanements," said S&P Associate Director Rob Marker. "However, we expect the impact will at least be partially mitigated by existing carriers including JetBlue, Breeze, and Allegiant — JetBlue is poised to become [the airport]'s largest carrier, and several airlines have expressed interest in expanding services. We have spoken with airport management and are monitoring operational changes, financial effects, and the airport's market position." The airport "maintains over 400 days cash on hand, which can provide short-term liquidity, and its bond covenants require a debt service reserve equal to 1.25x average annual debt service, offering additional support for bondholders."
"Spirit served passengers at airports across the U.S. system, and its exit may impact airport credits differently depending on hub size, governing airline agreements, demand, and route profitability," said Mohammed Murad, head of municipal credit research at PT Asset Management.
Usually, airports with a "healthy underlying travel market" have better flexibility handling the transition, he said.
Before Spirit ceased operations, "the demand backdrop remained supportive — travel has stayed fairly resilient with no meaningful pullback as of the end of 2025 versus the prior year," Murad said.
Airport traffic generally exceeds the pre-COVID peak and continued capital spending at airports may indicate "longer-term confidence in travel demand," he said.
Other airlines will replace Spirit's routes fairly quickly, analysts said. JetBlue has already picked up several of Spirit's international routes to Fort Lauderdale, for example, Kilcommons said.
But while other airlines step up to backfill some of Spirit's service, it won't lead to an increase in airport bond issuance, the sellside source said.
Airport issuance January through April was at $4.7 billion, with Ramirez projecting $27 billion for the year.
Despite the slow start in the first four months, the firm expects activity to begin accelerating in May, independent of Spirit's closure. This includes planned bond issuances for major airport capital investments, such as next week's long-delayed Houston deal, which will provide special facilities revenue bonds on behalf of United Airlines.
Any operational changes necessary to accommodate other airlines backfilling Spirit service will not affect airport capital programs in a "material way," the source said.
"If airlines need to raise funds, for whatever reason possibly related to assuming Spirit slots, assets, employees or other, it will be done independent of the airports," they said.
Moody's Ratings said Monday, "The shutdown is an adverse development for U.S. airports served by the low-cost carrier because it will reduce landing fees, terminal rents and non-airline revenue. However, the impact on airport credit quality will be limited."
Non-airline revenue, including parking, rental cars, food and beverages and retail, will most immediately be affected by Spirit's shutdown, Moody's said. However, airports will look to replace Spirit flights.
Pat Luby, head of municipal strategy at CreditSights said, "We do not believe this adverse development materially increases systemic risk for the sector; however, we do anticipate airport-specific near-term pressures as passengers, competing carriers and airport operators adjust to the exit of this ultra-low cost carrier."
"The challenge is that the loss of traffic from Spirit is going to be somewhat hidden by the greater challenges in the sector as a whole, with higher fuel prices, inflation, and economic situation. So instead of Spirit going out of business, and you're going to see X percent of dropped passengers, I think that Spirit dropped passengers are going to be subsumed by the overall drop," the sellside source said.
