Let’s move on to negative effects. A low-cost airline is an airline that generally has fewer comforts. Seats are allocated automatically by default. Hand-on luggage are strictly limited. Chance to up-selling other things such as cover insurance protection, entertainment, foods and snacks. Another negative point for a low-cost airline is probably be no refund given for cancellations and no change of dates once payment were fully made. In other words, lack of flexibility.
