The cost of traveling by air has been reduced dramatically mainly due to authorities around the world have been removing regulations, encouraging airliners to win the competition. Low budget airliners have been gaining the market share specially tourism destinations. Big airliners now form mainly 3 code share syndicates, trying to encourage passengers to use the same group of airliners or airlines network worldwide.
Frequent Flyer Program (FFP) provides what low budget airlines cannot afford, high quality customer service, giving mileage points not only by flying but as well as using certain hotel chains or rent-a-car services. Even the points can be gathered on the ground or by purchasing with credit card.
