A dozen airlines have agreed to include debit card charges in their upfront prices in UK online bookings rather than adding an additional surcharge in the final stages.
Ryanair, easyJet, Aer Lingus, bmi, Eastern Airways, Flybe, German Wings, Jet2, Lufthansa, Thomas Cook, Thomson and Wizz Air agreed to the change.
This follows enforcement action taken by the UK's Office of Fair Trading and also includes any charges levied for credit card bookings.
The UK government is considering legislation to ensure all companies follow suit.
In addition Monarch which charges for credit cards and not debit cards had voluntarily made the change last summer when the OFT said it was beginning its investigation.
Clive Maxwell, the head of the OFT, said: "This is a great outcome for the millions of people who buy flights online.
"It is important that the cost presented when they search for a flight is realistic and that they are not surprised by extra charges."
The OFT estimated the cost to consumers of card surcharges on airfares at GBP£300 million (USD$371 million) a year.
