Has anyone changed a flight with Ryanair. If so how much did it cost?\n\nI have booked to go to Lisbon in August for 4 people. Would like to change it to next year some time. Either that or lose £900.\n\nA quick google looks like it will be about 200-300 to change. Thinking about the sunk costs fallacy. \n\nHas anyone done this for a reasonable price?
