What the Airline Users Council fail to say is what was the BA fare before Ryanair and for the first 5 years of Ryanair operations and what is the equivalent fare on a sector where BA have no low cost competition ?
OK If you book last minute Ryanair can charge you full fare. I have spent decades paying BA and their subsidiaries over 300 pounds for a return trip to Southampton. Now Ryanair do Bournemouth for 2P return. Same happened on London services. Until Ryanair went up to 7, 8, 9 services a day BA kept their fares high now they are lower.
Good on you Ryanair. Keep your fares low and I'll fly with you rather than BA.
