Alicante's airport opened a few years ago. This was a very positive development for the community since locals and guests can now enjoy all the comforts of a modern airport.
There are several transportation options: there are buses run by Alsa that go to Benidorm (9€) or Alicante city buses that cost €2.60.
This airport is ideal for flights to UK, Ireland, and continental Europe. For example, it's one of the few airports with year-round flights to Iceland.
