Last updated: April 2026
Flight prices in 2026 are likely to rise, especially for long-haul routes from the UK, due to higher jet fuel costs and global supply disruption. If your travel dates are fixed, booking now is generally the safer option.
That said, not all routes behave the same way. This guide explains what is driving prices, which flights are most at risk of increases, and how to decide whether to book now or wait.
Quick decision guide
| Your situation | What to do |
|---|---|
| Long-haul flight with fixed dates | Book now |
| Short-haul Europe | Monitor prices |
| Peak season travel | Book early |
| Flexible travel plans | Set alerts and wait |
Why flight prices are under pressure in 2026
Airline ticket prices are heavily influenced by jet fuel, which is derived from crude oil. Jet fuel typically accounts for between 20 and 30 percent of an airline’s operating costs. When fuel prices rise or become unstable, airlines either increase fares or reduce route availability.
In 2026, several factors are combining to create upward pressure:
- Disruption to oil supply routes in the Middle East
- Tighter global supply of refined fuels such as diesel and jet fuel
- Airlines passing increased operating costs to passengers
- Continued strong demand for travel from the UK and Europe
Unlike normal seasonal pricing, this is being driven by supply-side risk rather than just demand. That makes prices more volatile and harder to predict.
Will flight prices go up in 2026
Prices are more likely to rise than fall, but increases will not be uniform across all routes.
Long-haul flights
Flights from the UK to destinations such as Thailand, the United States, and Australia are the most exposed to fuel price increases. These routes consume significantly more fuel and are more sensitive to changes in cost.
Airlines operating long-haul routes tend to adjust prices gradually as fuel costs increase. This means fares may rise steadily over weeks rather than spike overnight.
Short-haul European flights
Flights within Europe are more competitive, particularly on routes served by low-cost carriers. Even with higher fuel costs, airlines may absorb some increases to remain competitive, meaning deals can still appear outside peak periods.
Peak travel periods
Flights during school holidays, summer, and Christmas are most likely to see price increases. High demand combined with rising costs creates the strongest upward pressure on fares.
Should you book flights now or wait
The decision depends on your route, flexibility, and tolerance for risk.
Book now if
- Your travel dates are fixed
- You are flying long-haul
- You are travelling during peak periods
- You have found a reasonable fare
In these scenarios, waiting introduces more risk than reward. Prices are more likely to increase than drop significantly.
Consider waiting if
- You are flying within Europe
- Your dates are flexible
- You are willing to monitor prices and act quickly
Short-haul routes are more dynamic, and late deals can still appear depending on demand.
Why fuel prices affect flights more than most travellers realise
Fuel is one of the largest and most volatile costs for airlines. Even small increases in oil prices can have a noticeable impact on ticket pricing, especially on long-haul routes.
Airlines often hedge fuel costs months in advance, but these hedges are not perfect. When disruption continues over time, higher costs eventually feed through into ticket prices.
This is why price increases often appear gradually rather than immediately.
Could flight prices go down instead
There is one scenario where prices could fall. If economic conditions weaken and demand drops, airlines may reduce fares to fill seats.
However, this is less predictable and tends to happen unevenly across routes. It is not a reliable strategy for travellers with fixed plans.
How volatile are flight prices right now
Flight pricing in 2026 is more volatile than in typical years. External factors such as energy markets and supply disruption are influencing prices alongside normal seasonal demand.
This means prices can move faster and with less warning than travellers are used to.
For this reason, it is increasingly useful to think in terms of price risk rather than simply looking for the cheapest deal.
Smart booking strategies for 2026
- Choose flexible tickets where possible
- Compare departures from multiple UK airports
- Consider indirect routes instead of direct flights
- Book long-haul flights earlier and short-haul later
- Track prices regularly rather than checking once
Check current flight prices from London before they rise:

Booking directly with airlines can sometimes offer more flexibility, clearer baggage policies, and easier changes if your plans shift.
Frequently asked questions
Will flight prices go down in 2026
Prices could fall if demand weakens, but current fuel market conditions suggest upward pressure is more likely, especially for long-haul routes.
Is it cheaper to book flights early or last minute
In a rising cost environment, booking earlier is generally safer, particularly for long-haul and peak travel periods.
Are airlines already increasing prices
Airlines tend to adjust prices gradually. Increases often appear over several weeks rather than immediately.
The bottom line
Flight prices in 2026 are more likely to rise than fall, particularly for long-haul routes from the UK. This is being driven by higher fuel costs and ongoing global supply uncertainty.
If your travel plans are fixed, booking now is a sensible way to reduce risk. If you are flexible, there may still be opportunities, but expect more volatility than in previous years.
