I flew EZY a couple of weeks ago with my two children, I paid the extra money for priority boarding as I wanted to ensure we would be seated together, it worked fine at both Bale and Luton. If it hadnt worked I , like most, would probably not have bothered to ask for a refund as long as we were seated together but EZY, and the rest, can't hide behind the "no refunds" stated in their T&Cs. If they fail to provide a service which you've paid for they have to make amends and those who do pursue them in the courts will, generally, be successful. You can't sign away your rights....
