Ryanair Warns Fares Could Rise 20% in 2027: What It Means

Ryanair has warned that cheap flights may be about to get more expensive.
Chief executive Michael O’Leary says summer 2027 fares could rise by up to 20% if jet fuel prices stay where they are.
For millions of British and European holidaymakers, that is a significant warning.
This analysis explains what Ryanair has said, why fuel is driving the change and what it could mean for the cost of your next summer holiday.
What Ryanair Has Said
O’Leary gave the warning at a press conference in Warsaw on 29 September.
RTÉ reports that he said demand for air travel remained very strong because airlines had kept fares low, but that this could not continue with oil prices at current levels.
The exact range varies slightly between reports.
Reuters, via US News, quotes O’Leary as saying jet fuel costs would push summer 2027 fares up by 15% to 20%.
The Connexion reports a wider range of 10% to 20%, stressing that the estimate depends on jet fuel prices remaining at their current level.
Either way, the direction is clear.
Ryanair expects next summer to be noticeably more expensive than recent years.
Why Fuel Is the Problem
Fuel is one of the largest costs for any airline, and prices have surged in 2026.
Conflict in the Middle East has disrupted supply routes and pushed jet fuel close to its wartime peak, a trend we covered in detail in the October edition of Aero Insight.
Ryanair is usually well protected from fuel spikes.
The Connexion notes that the airline has historically hedged around 80% of its fuel needs a year in advance, but is currently hedged at only about 40%.
That leaves Ryanair far more exposed to current prices than usual.
Infos Tourisme reports that if Ryanair’s average fuel cost rose from around $80 to $100 a barrel in its next financial year, its annual fuel bill could increase by €1.5 billion.
No airline can absorb a cost increase of that scale without passing some of it on to customers.
No Fuel Surcharges, Says Ryanair
Ryanair is keen to stress that it will not add separate fuel surcharges.
The Connexion quotes O’Leary saying that Ryanair will not levy a fuel surcharge, but that legacy airlines certainly will next summer.
That distinction matters for the airline’s marketing. Fuel surcharges are unpopular with passengers, and Ryanair wants to keep its headline fares simple.
However, the outcome for travellers may be similar.
Whether the extra cost appears as a surcharge or a higher base fare, passengers will still pay more.
O’Leary also argued that rivals are no better placed.
The Connexion reports him saying that none of Ryanair’s competitors are well hedged either.
The Longer Term Picture
O’Leary went further than next summer.
The Connexion reports that he outlined a scenario in which jet fuel stays at $140 a barrel for five years, pushing the average fare from around €50 today to between €80 and €90 over the following six to eight years.
That is a hypothetical scenario rather than a forecast.
Fuel prices could fall if conflicts ease, and Ryanair’s estimates would change with them.
Still, it highlights how dependent the low fare model is on affordable fuel.
The ultra cheap fares that defined European travel for two decades rely on cost conditions that may not return quickly.
A Push Towards Consolidation
O’Leary also made a characteristically provocative prediction.
UNN reports that he said higher fuel prices would accelerate the failure of loss making airlines.
He suggested this could lead to European consolidation around four major groups: British Airways, Lufthansa, Air France and Ryanair.
There is evidence that weaker airlines are struggling. Smaller carriers across Europe have cut capacity this year, and fuel costs have been a central factor.
For Ryanair, consolidation would be good news.
Fewer competitors would give it more pricing power and more opportunity to grow into markets left behind by failing rivals.
Ryanair Is Still Growing
Despite the warning, Ryanair is not cutting back.
Reuters reports that it will base three more aircraft at Warsaw Modlin, taking its fleet there to nine as part of a $300 million investment, and will add 18 flights from Warsaw’s Modlin and Chopin airports this winter.
The airline is also considering Poland for a new engine shop, with a decision expected by the end of the year.
Fleet growth is continuing too. Reuters reports that O’Leary still expects the first 15 Boeing 737 MAX 10 aircraft in spring 2027, despite the latest certification delay.
We examined the MAX 10 timeline in our piece on when Ryanair receives its 737 MAX 10 aircraft.
The combination of growth and higher fares is not a contradiction. If capacity across Europe is constrained while demand remains strong,
Ryanair can fill more aircraft at higher prices.
What It Means for Your Summer 2027 Holiday
For travellers, the message is to plan ahead.
If fares do rise, the cheapest seats are likely to sell first, and late bookings could become noticeably more expensive.
Booking early has always been the best way to secure low Ryanair fares.
That advice becomes even more important if the overall fare level is rising.
Be flexible with dates where possible.
Flying midweek or outside school holidays usually remains cheaper, even in a higher fare environment.
Compare total trip costs, not just headline fares.
With other airlines expected to add fuel surcharges, the cheapest option may depend on how each airline presents its pricing.
Families should budget carefully.
Infos Tourisme notes that a few extra euros per flight can add up quickly for a family of four across several sectors.

Will Fares Really Rise 20%?
It is worth treating the figure with some caution.
Airline chiefs often use fare warnings to manage market expectations, and Ryanair’s estimate depends on fuel prices staying high.
If fuel falls, the increase could be much smaller.
If it rises further, it could be larger.
What is clear is that the era of very cheap European flights is under pressure.
Higher fuel costs, consolidation and strong demand all point in the same direction.
The Bottom Line
Ryanair’s warning of 15% to 20% higher fares next summer is a signal that travel costs are rising across Europe.
With hedging lower than usual and fuel prices high, even Europe’s biggest low cost airline cannot hold prices down indefinitely.
Book early, stay flexible and watch fuel prices.
They will determine how much your summer 2027 holiday really costs.
