There are so many reasons. I always fly with low-cost airlines, because it's cheaper than the normal airlines. We almost always choose these airlines instead of car.
Every continent has got some low-budget airlines. I think the cheapest airlines that you can fly from Hungary is Wizzair. There are other airlines too. For instance Easyjet, Ryanair (it is UK a 
specialist) and Skyeurope but it ran out of business.
If you choose low-cost airlines to travel, you have to book on the net and if you want ,you can also check-in on the internet. There is just one difference from other services; you don't get food on the board. If you are a small family and want to go somewhere not too far you should choose any of these airlines. Or if you want to go to a more distant destination you should choose low-budget airlines as well.
For example: You want to go to Venice. The plane ticket is about 6.000 Ft without baggage but I think you can pack in a smaller bag which you can bring on the deck and it is free. If you are 4 people the plane ticket is 24.000 Ft and that's the travelling charge. But if you go there by car 1 fuel up costs around 20.000 Ft and you can't drive this trip at this cost... So in a lot of cases the low-cost airline is cheaper than normal airlines or car.
