Two leading European airlines have been compelled to adjust their ticket prices, with an increase of nearly £100, as they grapple with escalating fuel costs.

The surge in jet fuel prices has been fueled by Iran’s blockade of the Strait of Hormuz, a situation that has persisted since conflict erupted on February 28.

In response, KLM and Air France, operating under the same corporate umbrella, have made the decision to raise their fares for a second time.

Last month, these airlines had already announced a price hike due to the burgeoning jet fuel expenses.

According to reports from The Sun, economy class passengers have seen an increase of €50 (£43.47) for round trips.

In a move reflecting the ongoing challenges, Air France-KLM has confirmed another fare increase this week.

Many of the company’s long-haul round trips will see another another €50 – totalling to €100 (£87).

Meanwhile, a round economy route will be increased by €10 (£8.69) and routes to America, Mexico and Canada will see a €70 (£60.85) rise.

The Daily Mail has contacted Air France-KLM for comment. 

Air France-KLM are not the only carriers to have to react to the rising cost of jet fuel, plenty of others across Europe and around the world have made adjustments too.

One Spanish carrier, Volotea, has even reportedly been pushed to demand extra fees from some passengers after they have booked and paid for their flight. 

The budget airline apparently added a small fuel surcharge and asked travellers, who had already covered their costs, to pay in an email, according to Simple Flying. 

Some people online claimed they were asked to cough up between $8 to $11 (£5.90 to £8.10).

The airline seems to be using a clause in its conditions of carriage – reportedly referred to as its ‘Fair Price Promise’.

Volotea’s website has a ‘Fuel Cost Adjustment’ clause listed under section four, Prices, of its conditions of carriage. 

The clause outlines how passengers will have been informed of the possibility of a price change during the booking process and explains how rising fuel prices are the cause. 

Other airlines have made adjustments too, including Volotea, who has even reportedly been pushed to demand extra fees from some passengers after they have booked and paid for their flight

 It states: ‘In the event of extraordinary variations in fuel prices affecting international energy markets, Volotea may apply a limited and temporary adjustment to the ticket price prior to the scheduled departure of the flight.

‘Any such adjustment will be calculated in accordance with the methodology, thresholds and limits published on Volotea’s website.

‘Passengers will be informed during the booking process of the methodology applicable to any adjustment resulting from increases or decreases in fuel costs, which may lead to a corresponding increase or decrease in the price of their Ticket. 

‘The exact amount of any such adjustment will be communicated to passengers prior to departure, once the applicable fuel cost variation has been determined. 

‘Such adjustments will only apply to passengers who have been informed of this possibility during the booking process, allowing them to make an informed decision before completing their purchase.

‘By completing their purchase after being informed of the possibility of any adjustment to the Ticket price, passengers acknowledge and accept that such adjustment may be applied and authorise Volotea to charge any corresponding increase, or reimburse any decrease, using the same payment method used to purchase the Ticket.’

The clause appears to be a new addition to Volotea’s terms, with previous versions of the website from earlier this year not showing the ‘Fuel Cost Adjustment’ section. 

It comes as jet fuel prices have surged with the Strait of Hormuz being blocked by Iran since war broke out on February 28. 

Around 20 per cent of global oil and liquefied natural gas supplies pass through the strategic passage in the Gulf. 

A spokesperson for Volotea told the Daily Mail: ‘The airline has chosen not to introduce arbitrary fixed fuel surcharges, instead adopting an innovative approach that combines flexibility, fairness, freedom of choice, and transparency. 

‘Within this framework, the Fair Travel Promise has been introduced for bookings made from the 16th of March 2026 onwards, an exceptional and temporary measure, designed to protect travellers and ensure operational stability, while minimizing the impact amid evolving global conditions.

‘Volotea will use fuel market prices, from publicly available sources, seven days before departure as a reference and, if necessary, adjust ticket prices up or down accordingly. 

‘In the event of an increase, the airline will apply a surcharge up to €14 per passenger, per flight; conversely, if prices decrease, the company is committed to refunding customers the difference, up to the same maximum amount.

The core element of the Fair Travel Promise is flexibility, the true strength of the initiative: passengers can modify their flight or cancel their booking free of charge up to four hours before departure, an especially beneficial feature not commonly offered by airlines.’

They added: ‘Volotea will continue to closely monitor market developments and, in parallel, keep passengers informed in a timely manner, ensuring maximum transparency and flexibility, while enabling informed travel decisions and offering greater peace of mind.’
