We have used this airline and route on 7 occasions. Prestwick is easy to get to; parking is not cheap but handy and San Javier is only 20 minutes drive to Villamartin where we stay. It's a 3 hour flight and is like any other Ryanair flight - it has had its moments but without actual incident over the years. We could use Alicante but it's further to drive and busier. On the whole we find it reasonably priced and convenient and would recommend it. However, it's always wise to scrutinise the airline's changes to its t's and c's from year to year.
