There are a lot of airlines offering very good prices at the moment. Even BA's domestic and European flights have become (imho) exceptional value for money if booked a couple of weeks in advance. My Travel Lite, EasyJet, BMi.. the list is endless.
MOL has probably just alienated a fair number of passengers, able-bodies included, with this gesture, regardless of whether he is right or wrong re. liability of costs.
I hope they vote with their feet and pay just a few quid extra to fly with another, more sympathetic, company.
