Ryanair have a free-seating method of boarding passengers, but why, when the flight is only half-full, do they insist on restricting seating for take-off to the front and rear rows only, filling all 6 seats across, and leaving the entire mid-section empty? Aircraft trim? B737 take-off handling or loading peculiarity?
You are free to change your seat after take-off, but I have never seen this rule applied by other airlines....
