It might be much more sensible getting flights to Istanbul (much more flights, bigger airport) and then flying with local budget airlines to Antalya. When booked well in advance, as in 1 month or more before, the local flights start as low as 20 Euro one way. So you might want to look into flying into Istanbul and then taking a local flight to Antalya. We will probably be able to help you arrange the local flight after registration.
