If you follow the link, you get to a comparative table of "Ryanair" and "High Fare Airlines" services. Under "Rapid response to passenger complaints" they have Ryanair - "Yes (7 days)", High Fare Airlines - "No (28 days)".
Easy to do, of course, when you've got 4 people (or is it now 5?) churning out identikit letters to complaining pax telling them to, as it were, "go forth and multiply".
