One of the Portuguese Airlines "Air Luxor", No no no it's not from Egypt, it's from Portugal, are introducing a system called "Light" Air Luxor Light... In which 10% of the aircraft capacity goes to those so called Light prices, for example a Lisbon-London ( LGW ) costs an amazing 29Euros ( Airport taxes not included and only one way fare, in small prints ), And no Air Luxor is not a Low Coast Airline.
They are also introducing another domestic system in which you buy a "monthly pass" and you can fly anytime you want within Portugal for only 200Euros a month.
Now, i dont understand how can they make any money if costs will be superior than profits.
