Spirit Airlines Shuts Down as Strait of Hormuz Fuel Costs Pile On

Harry Reid International served 16 Spirit markets; rival carriers are offering rescue fares through mid-week.

Spirit Airlines ceased all operations as of midnight Saturday after negotiations over a possible government bailout collapsed, leaving passengers across the country without flights and putting Las Vegas travelers among those scrambling for alternatives. Harry Reid International Airport confirmed the shutdown affects 16 markets Spirit served from Las Vegas, though an airport spokesperson said every one of those destinations is currently served by at least one other carrier.

What Happened to Spirit Airlines

Spirit declined to comment Friday on reports it would shut down, but by Saturday morning the airline had confirmed the end of operations. The closure follows a second bankruptcy filing the carrier made last year. Transportation Secretary Sean Duffy, asked about Spirit's collapse during an ABC News interview Sunday, pointed to the airline's failed merger attempt with JetBlue. 'Spirit tried to merge with JetBlue. The Joe Biden-Pete Buttigieg administration and DOJ tanked that deal,' Duffy said. 'Immediately after that, they filed for bankruptcy. They were having financial problems, Martha. They filed for bankruptcy again last year. They were bleeding money. And so, this was in the works for some time.'

The shutdown puts tens of thousands of passengers in travel limbo nationwide. At Harry Reid International, the airport's customer service staff are available on site to assist travelers, and the airport says it 'remains fully operational, with all other airline services continuing as scheduled.' Passengers who booked through a third party are being directed to contact their booking provider or credit card issuer to inquire about refunds.

Rescue Fares From Competing Carriers at Las Vegas

Several major carriers moved quickly to absorb displaced Spirit customers. Southwest Airlines is offering special fares at ticket counters for eligible routes through 11:59 p.m. CDT on Wednesday, May 6. Southwest's pricing tiers for domestic travel in affected markets are $200 for trips up to 500 miles, $300 for 501 to 1,000 miles, and $400 for routes longer than 1,000 miles.

JetBlue is offering one-way fares of $99 on all routes Spirit operated as of April, available through May 6, with valid proof of a Spirit ticket for the same route. United is capping most one-way fares where Spirit flew, with non-stop fares at $199 and longer or connecting flights no higher than $299 in United Economy. Delta is offering reduced, nonrefundable rescue fares in affected markets for five days. Frontier is offering 50% off base fares and a $199 GoWild All-You-Can-Fly Summer Pass, and says it plans to expand with nine additional routes and 15 additional daily flights across 18 former Spirit markets. Allegiant is offering 50% back in points for Spirit customers who join its Allways Rewards program through May 12 and says it will temporarily hold fares steady on routes that overlap with Spirit.

Fuel Costs and the Strait of Hormuz

Elevated fuel costs have been a pressure point across the airline industry since the conflict with Iran began. The national average price for a gallon of gasoline stood at $4.45 as of Sunday, according to AAA, up from $2.98 before the war started. AAA reported that prices jumped nearly 30 cents in the week prior to Sunday alone.

The Strait of Hormuz, through which a significant share of the world's oil supply flows, remains a chokepoint. Pentagon officials have briefed lawmakers that American forces might need six months to clear mines Iran laid in the strait. University of Houston energy economist Ed Hirs told The National News Desk that some oil trade through the strait might resume before mines are fully cleared, but damaged facilities in the region could still throttle Persian Gulf oil flows. Hirs said U.S. gas prices should remain elevated 'at least through the end of the year, at a very minimum,' describing the strait as a 'bottleneck' for global oil supply.

Duffy offered a more optimistic assessment. 'Once the strait opens, you'll see prices come down, come down immediately,' he said. 'And again, there's going to be a tail to that. It's going to take time to get back to where we were before this conflict began, but you're going to see, I think, immediate relief once the strait opens.' Duffy acknowledged he is at the Department of Transportation rather than in the energy sector, and that his view reflects briefings he has received.

How Americans Are Responding to Higher Prices

A Washington Post-ABC News-Ipsos poll conducted April 24-28 found that higher gas prices are already changing behavior. Forty-four percent of respondents said they were cutting back on driving, 42% said they were cutting household expenses, and 34% said they had changed their travel or vacation plans because of elevated prices.

Duffy framed the conflict in broader terms during his Sunday interview, saying President Donald Trump views Iran as 'the most destabilizing force in the world for 40 years' and is focused on preventing Iran from acquiring a nuclear weapon alongside his stated goal of American energy dominance.

The take

Spirit's collapse fits a pattern that budget carriers have struggled to escape since the pandemic reshaped travel demand. The ultra-low-cost model depends on high seat utilization and razor-thin margins, which leaves almost no buffer when fuel prices spike. Spirit had already been weakened by its failed JetBlue merger and two bankruptcy filings; the surge in jet fuel costs tied to the Strait of Hormuz disruption appears to have been the final pressure that made a bailout deal untenable. For Las Vegas, which has historically benefited from Spirit's low base fares driving leisure travel volume, the short-term impact will be felt by price-sensitive travelers who relied on the carrier's sub-$100 fares. The rescue fare programs from Southwest, JetBlue, United, and others are a standard industry response to sudden carrier failures, but those fares are temporary and typically higher than what budget carriers charged at baseline. Frontier's announced expansion into former Spirit markets is the more structurally significant development; budget capacity in those markets may partially recover over the summer. On the fuel side, the gap between Duffy's optimism and Hirs's assessment reflects a genuine uncertainty in the market. Historically, oil price relief after a supply disruption has lagged the physical reopening of shipping lanes, because refinery throughput, inventory drawdowns, and shipping logistics all take time to normalize. Six months of mine-clearing, if the Pentagon's estimate holds, would push any meaningful price relief well into late 2025.

Why it matters

For Las Vegas, Spirit's shutdown removes one of the few carriers that kept base airfares competitive on leisure routes, which are the lifeblood of the city's tourism economy. Budget travelers who drove visitation numbers may face meaningfully higher ticket prices through at least the summer. Combine that with gas prices nearly 50% above pre-conflict levels and a poll showing a third of Americans have already changed vacation plans, and the near-term outlook for Las Vegas visitor volume carries real downside risk.

What’s next

Southwest's rescue fares for Spirit customers are available at ticket counters through 11:59 p.m. CDT on Wednesday, May 6. JetBlue's $99 rescue fares are also available through May 6. Allegiant's points promotion runs through May 12. Frontier has announced plans to expand with nine additional routes and 15 additional daily flights across 18 former Spirit markets this summer, though specific launch dates were not disclosed in available reporting.
