Could anybody give me ideas how is the cheapest and easiest to get from Barcelona's airport to Alicante.
By hitch-hiking. Or where can I check buses?
Thank you:

Check into the train. I was going the opposite way (Alicante to Barcelona) last year, but found the schedule met my needs and the price was very reasonable. Plus I thought the train was much more comfortable than the bus.

The metro will take you to Sants (train/metro station) and from there you can catch the train (RENFE) to Alicante.

Good luck with your trip!
