How has air travel change the way people spend their holidays?

Previously, very few people could travel abroad because there wen't any means of transport such as aircraft, or it was too expensive. People went tu nearby places such Salou or Tarragona. They had to take other transportation like the train, the transport of the poorest people the most used at that time, or car, but very few people had one, because it was too expensive. Today, everything has changed. Now many air companies offer a lot of flights for very little money. You can go to the other side of the world in less than 24 hours. However, in the past you spent days and days before you arrived and you had to go by boat and it was much slower.
