A dozen airlines have made a decision to include debit card charges in their so-called headline prices, rather than near the end of the process when booking online.
The carriers, which include popular budget firms Ryanair and Easyjet, will also clarify credit card costs during initial booking sequences.
The companies have agreed to the change after an investigation by the Office of Fair Trading (OFT), and the Government has considered making all carriers follow suit.
The other airlines who have decided to change their online booking process include Aer Lingus, BMI Baby, Eastern Airways, Flybe, German Wings, Jet2, Lufthansa, Thomas Cook, Thomson, along with Wizz Air.
Monarch, an airline which adds a surcharge only for credit cards, altered its pricing to include the charge in the headline price last year.
"It is critical that these charges are transparent and not sprung on shoppers towards in the end of the booking process," the OFT said.
The £6 fee for administration charged by Ryanair will from August 1 onwards be included in the advertised headline rate and in its online headline rate by December.
Easyjet's £9 booking fee was also already shown in its advertised prices as it preceded Ryanair's policy shift.
Eastern Airways, Easyjet, Flybe, German Wings, Lufthansa, Thomas Cook, Thomson and Wizz Air have also altered marketing and pricing structures.
The changes for the other airlines' advertised prices are expected to be enacted within a month ahead of the headline rate change.
However, it is not all good news for consumers as a surcharge is still permissible for credit card bookings as it is a more expensive process for the firms.
