United flight cuts begin as jet fuel prices spike. FAA restrictions at Chicago O’Hare are making the busy summer schedule even tighter.
United Airlines is the first to take action.
This week, United announced it will cut about 5 percent of its planned flights over the next few months due to rising jet fuel prices following Operation Epic Fury and the growing conflict with Iran. The move is a direct response to higher costs and shows how the industry is having to adapt, even as some airlines continue to grow.
This is happening at a particularly complicated moment for Chicago O’Hare (ORD).
In recent months, both United and American Airlines have been aggressively expanding at the airport, adding flights, increasing frequencies, and reconnecting a wide range of markets to one of the country’s most important hubs. That includes cities like Kalamazoo (AZO), Erie (ERI), Lincoln (LNK), Lansing (LAN), Tri-Cities (TRI), Champaign-Urbana (CMI), Bloomington-Normal (BMI), Allentown (ABE), and Columbia (CAE).
Now, that expansion is facing two constraints that are converging simultaneously.
At ORD, the Federal Aviation Administration (FAA) plans to limit flights this summer because airlines scheduled more flights than the airport can realistically handle. At the same time, rapidly rising fuel prices are making airlines rethink which flights make financial sense.
Each of these challenges would be manageable on its own.
Together, they are forcing airlines to adjust their plans.
A Tactical Pullback in a High-Fuel Cost Environment
United CEO Scott Kirby described the cuts as a short-term response to higher costs, not a change in the airline’s long-term plans.
Jet fuel prices have more than doubled in the last three weeks. If prices stay this high, Kirby said it could mean an additional $11 billion in yearly fuel costs. For context, United’s best year made less than $5 billion in profit.
Meanwhile, demand is still strong. Kirby said United had its ten biggest revenue weeks ever in the past ten weeks.
This situation is key for United right now. Planes are full, but higher fuel costs are cutting into profits.
“We’re ready, we have a plan, and we’re going to continue executing that plan,” Kirby said in a recent update.
We’re ready, we have a plan, and we’re going to continue executing that plan.

United is cutting flights that can’t cover these higher costs right now. The airline will reduce about 3 percent of off-peak flights, such as red-eyes and flights on less busy days like Tuesdays and Wednesdays. It has also suspended service to Tel Aviv (TLV) and Dubai (DXB) and cut about 1% of capacity at Chicago O’Hare.
Altogether, this means about 5 percent of planned flights will be cut for now, but Kirby expects to bring back the full schedule by fall 2026.
Kirby stressed that these cuts are targeted. United is not laying off staff or delaying new planes. The airline still plans to take delivery of about 120 new aircraft this year, including 20 Boeing 787s, and over 100 more by 2028.
United is planning for oil prices to possibly reach $175 per barrel and stay above $100 until 2027.
Demand Is Strong. Margins Are Under Pressure.
This slowdown is not because of weak demand.
Recent bookings show that travel demand is still strong, even with higher fares. But airlines have thin profit margins, and fuel is still one of their biggest costs.
When fuel prices rise this fast, even strong demand can’t make up for the higher costs on every route.
That’s why airlines start by cutting less profitable flights first.
United is the first major US carrier to announce major flight cuts due to high fuel prices. Other airlines have said they might do the same if prices stay high, and some international airlines have already changed schedules or raised fares.
The airline industry is reaching a point where just growing isn’t enough. Even with strong demand, making a profit is now the main challenge.
Chicago O’Hare: Expansion Meets Operational Limits
While United is cutting flights, Chicago O’Hare – United’s largest hub – is also facing its own capacity constraints.
The FAA has stepped in after airlines scheduled more than 3,080 daily operations on peak days for the summer 2026 season. The agency has indicated that approximately 2,800 daily operations is a more sustainable level given current runway, terminal, and air traffic control capacity.
That gap prompted the FAA to initiate a schedule reduction process to prevent widespread delays and operational disruption.
This creates a second layer of pressure.
Both United and American have been rapidly expanding at ORD. United has been pushing toward roughly 780 daily departures, while American has been building toward more than 500. The combined schedules would have made this summer one of the busiest in the airport’s history.
Now, airlines have to change those plans just weeks after making them.
For United, part of its announced 5 percent capacity reduction is already tied directly to anticipated cuts at O’Hare as the FAA process moves forward.
This means United is not just reacting to higher fuel costs. It also has to adjust because O’Hare can’t handle all the growth it had planned.
The Ripple Effects Across the Network
When airlines cut flights, the impact goes beyond just one city or market.
United says it will mainly cut less profitable flights, especially those during off-peak times or on routes that make less money. This is a common strategy when costs go up.
This situation is more complicated because several problems are happening at once. Fuel prices are rising fast, and it’s not clear how things will turn out. FAA limits are cutting available flights at a major hub, and airlines have just expanded their schedules, especially at O’Hare.
That combination requires adjustment across the network.
Some routes may see reduced frequencies. Others could be delayed or modified seasonally. In some cases, newly announced service may not launch exactly as originally planned.
This is particularly relevant for recently added or expanded routes at ORD, including the recent service announcements to small and mid-size communities across the US.
There has been no indication that any of these specific routes are being cut.
But flights to these types of communities are usually more affected by cost changes and schedule adjustments. When airlines update their schedules, these types of routes are often among the first to see changes in frequency or timing.
These routes are not the reason for the cuts.
But these routes may be where the effects show up first. For some small and mid-sized communities, these new flights were a lifeline for airports that have struggled since COVID-era service reductions.
The Bottom Line
United says these flight cuts are temporary and plans to bring back the full schedule by fall 2026.
United’s long-term plans haven’t changed. The airline is still getting new planes and investing in its hubs and infrastructure.
But the short-term situation is changing.
Fuel prices are going up quickly. Limits at big hubs like Chicago O’Hare are slowing growth. Airlines now have to rethink how many flights they can run with today’s costs.
As a result, airlines are making adjustments.
Just a few weeks ago, the focus at ORD was on growth, with more flights, more destinations, and better connections.
Now, the focus is on finding balance.
How airlines manage this balance in the next few months will affect not just the summer 2026 schedule, but also the future of network planning for US airlines.
