Hi, yes, let's hope there are more competitive rates, and services, as the airport gets up and running - because there is certainly no sign of them yet.
As I have probably stated before, in May 2017, I booked a Resort Hopper (it was a mini bus with just four stops) from Alicante airport to Benidorm, and return. The price was just 25 euros.
If Corvera wants to encourage customer flow into the Murcia region it will have to seriously, 'Up it's game.' Time will tell.
