A Spanish consumer rights organisation has launched a challenge against airline Volotea over its new pricing system that links ticket costs to fuel prices, raising concerns about possible violations of consumer protection rules.
The consumer group Facua has called for an official investigation into the airline’s policy, which allows post-booking adjustments of up to €14 per passenger depending on changes in fuel costs.
Volotea introduced the temporary measure in March after global oil and jet fuel prices rose following geopolitical tensions. The airline says the policy applies only to bookings made after its introduction and that customers are informed before purchase.
According to Facua, the system may breach EU consumer rules, which require airlines to clearly show the full ticket price upfront and avoid changing costs after purchase. The group argues that passengers should not face additional charges once a ticket is confirmed.
The issue has also drawn attention from the European Consumer Organisation, which supports stricter transparency rules and says passengers should not be subject to extra surcharges after buying a ticket.
Volotea defends its approach, saying the pricing model is transparent, based on publicly available fuel benchmarks such as Brent crude prices, and does not generate extra profit. The airline says it is designed to reflect real-time changes in fuel costs.
Under the system, the airline checks fuel prices shortly before departure and may add a surcharge of up to €14 if costs rise above a set threshold. If fuel prices fall, passengers could receive partial refunds.
The Spanish Consumer Affairs Ministry has confirmed it has received the complaint and will review the policy.
Facua argues that the maximum surcharge would only apply when oil prices exceed a certain level, and says the system creates uncertainty for passengers over final ticket costs.
Volotea, based in northern Spain, says most customers have accepted the policy and continue to travel, claiming high compliance since the system was introduced.
The case is now under review, and regulators will decide whether the airline’s fuel-linked pricing model complies with European consumer law or requires changes.
