EasyJet had said it will not add surcharges to pre-booked flights or package holidays, or any new bookings for summer 2026.
The group stressed it was not currently experiencing any disruption to its supply of jet fuel, adding all its flights and package holidays were continuing to operate normally.
Similarly, Tui managing director UK and Ireland Neil Swanson said the airline and operator not add fuel surcharges this summer.
By contrast, British Airways parent IAG said it would make price adjustments to reflect higher fuel costs, stressing it was "not immune" to the effects of the war in Iran.
