I was refreshing flight results when the cheapest fare winked out. You feel a small, furious economy rearranging itself under your plans. I closed the tab and realized summer travel just got meaner.
On my screen Spirit flights vanished from the grid.
I’ve followed fares long enough to know what a low-cost carrier does to a market. Spirit’s routes—less than 2% of U.S. flights, by the Wall Street Journal—served as the mental floor for what a ticket could cost. When that floor disappears, bigger carriers quietly move their pricing up to fill the gap, and you’re left paying for a bargain that no longer exists.
The gate agent handed me a baggage fee receipt and shrugged.
You’ve already noticed ancillary charges rising; that’s airlines shifting costs onto passengers because their own fuel bills have exploded. After Feb. 28, the conflict that shut down about 20% of global oil transits through the Strait of Hormuz drove jet fuel costs up sharply—so sharply that European and Asian carriers began canceling flights by the millions, the Financial Times reports. U.S. airlines have responded by hiking baggage and service fees while keeping base fares sticky upward.
Why are flights getting more expensive?
Because fuel is now a dominant expense in airline margins, and when supply routes are threatened prices don’t trickle up—they surge. Kayak’s dashboard shows averages rising: domestic fares jumped about 25% since early 2026, international fares about 62%. That’s not small-change arithmetic; it’s a systemic shock to route economics and customer expectations.
The Kayak chart on my laptop lit up with city names and new prices.
Look city by city and you see the arithmetic: a flight to Atlanta averaged $222 (€206) before the war and sat at $263 (€245) by April 27; Salt Lake City moved from $376 (€350) to $413 (€384); Honolulu climbed from $534 (€497) to $628 (€584). When Spirit abandoned routes between Q2 2024 and Q2 2025, the Journal found average fares on those routes spiking 23%—like a deflating balloon that suddenly pulls the whole room inward.
How will Spirit Airlines closure affect fares?
Spirit’s market share was small on paper but large in perception. When a low-cost anchor vanishes, competing carriers test higher yields. Routes that saw Spirit leave earlier already jumped roughly 23%; now that the airline is gone more broadly, those upward pricing tests will spread beyond a few routes into the national fare baseline. Kayak’s city-level data is your window into that spread.
In the terminal people ask if they should still fly this summer.
You’re weighing time against money, and gasoline tells the same story. The U.S. average for a gallon was $4.48 (€4.17) on Tuesday per AAA, up from $2.98 (€2.77) before the conflict—so swapping planes for cars isn’t the cheap fix you’d hoped for. Meanwhile, 1,500 commercial ships and roughly 22,500 crew and passengers remain stalled near the Strait of Hormuz, the Pentagon’s leadership has said, and Project Freedom’s attempts to reopen the route have met heavy resistance.
Should I book now or wait?
I can’t predict the exact week fares will peak, but I can tell you how markets move: when supply tightens and an anchor competitor disappears, sellers test higher prices quickly. If your plans are firm, locking in a fare now buys certainty; if you’re flexible, monitor Kayak, Google Flights and airline alerts and be ready to pounce on short windows. Either way, don’t assume prices will revert to pre-crisis levels rapidly—political risk has inflationary legs.
President Trump has promised Project Freedom and suggested the market will cool; he’s wagered the war will be short and fuel prices manageable. He’s publicly said he expected oil to spike into the hundreds of dollars and then settle—he currently sees it at about $102 (€95). Yet the practical result so far is rising jet fuel and airlines passing that expense to you in fares and fees. The war’s stated goals have shifted from regime change to nuclear prevention, but the immediate, measurable impact for most Americans is higher transportation costs and shrinking travel options.
Airlines and platforms—Kayak, the Wall Street Journal’s reporting, the Financial Times’ seat-cancellation tallies, AAA’s pump data, Axios’ shipping updates—are all offering pieces of the same map. You’ll hear arguments that markets will self-correct; you’ll hear officials insist supply lines will reopen. For now, the market is behaving like a long line of price tags falling one after another—each customer pays for the one before them.
Thanks, Mr. President: you called it Project Freedom, but whose wallet is paying for it?
