From - you guessed it - Ryanair.
Responding to news that British Airways has created a web calculator for users to compare fares against low cost carriers, Ryanair's Stephen McNamara said:
"It wouldn't matter if BA put pictures of naked women on their website, passengers will always go to ryanair.com to book the lowest fares. That is why Ryanair will carry over 67 million passengers this year - more than double BA's declining figure of less than 30 million".
