The advantages and disadvantages of cheap flights
Around the world there are more low cost airlines so we can flight for a lower price. However, Latin America doesn't have as many airlines as in Europe.
The most important advantage is that you pay 39 euros for a flight in Europe. Although, in summer you can pay 100 euros for a flight. Another advantage is that you also have service of airline (?).
On the other hand, it is possible you can not carry more than 10 kilograms. Another disadvantage is that the flight is scheduled early in the morning.
In my opinion, if you can buy cheap flights, you can visit other countries without paying much. The problem is that people do not know that there are low cost airlines around the world.
