If your next flight costs noticeably more than the last one, you are not imagining it. US government data show airline fares were 22.4% higher in September than a year earlier, as the conflict around the Strait of Hormuz sent jet fuel prices soaring. Airlines around the world are adding fuel surcharges, trimming capacity and rerouting flights — and passengers are paying the price.
Key takeaways
- Fuel is typically one of an airline’s largest costs, so price spikes pass through quickly.
- Carriers are cutting less profitable routes, reducing seat supply.
- Flexible dates, early booking and alternative airports remain the best ways to save.
Why flying costs more
Jet fuel is refined from crude oil, and with Brent crude trading near $110 a barrel in mid-October, airlines face sharply higher costs. Some carriers have also had to reroute flights around conflict zones in the Middle East, adding hours of flying time and burning more fuel. Fuel surcharges on international tickets have risen for several consecutive months in parts of Asia, and many airlines have raised baggage and seat-selection fees.
Capacity cuts tighten supply
To protect margins, airlines are reducing frequencies on routes where demand is softer and parking older, less fuel-efficient aircraft. Fewer seats combined with steady demand means higher fares, especially during peak periods such as the November and December holidays.
Higher fares don’t necessarily mean bumper airline profits — fuel is eating much of the extra revenue.
How to save on flights now
- Book earlier for the holidays: Prices for peak dates tend to rise as seats fill.
- Be flexible: Midweek departures and shoulder-season trips are often significantly cheaper.
- Compare nearby airports: Secondary airports can offer lower fares and fees.
- Set fare alerts: Track routes and book when prices dip.
- Read the fine print: Compare the total cost including bags and seat selection.
- Consider rail: For shorter European and Asian trips, high-speed rail can rival flying on time and cost.
The outlook
Fares will likely stay elevated as long as oil prices remain high and shipping through the Gulf is disrupted. Any diplomatic breakthrough that reopens the Strait of Hormuz would ease fuel prices relatively quickly, though airlines may be slow to cut fares. Get more practical advice in our Travel section.
