The buses which operate from Palma Airport are Line 1 which runs between the airport and Palma city centre and bus route 21 links Palma airport with S'Arenal. I have used both on several occasions and they are pretty reliable and usually on time.
Both run on a linked circle route (just keep going round and round) and you will find timetables at Palma and Airport bus stops. They are easily recognisable being white with green and blue arrows on the bodywork.
The costs of both buses below are very reasonable at €2.50 single fare and you can find out more from their website EMT Palma Telephone: +34 971 214 444
Line 1 connects the airport with the sea front at Palma.
The bus leaves Palma Airport arrivals floor across from the car park at regular 15 minute intervals and also stops at Departures Floor 2. Cross the car park and walk for about 2 minutes to find the bus stop. If you are carrying heavy luggage use the automated walkway to take you there.
Buses have their own electronic messaging system on board to tell you the next stop. Operating times are:
Winter (November -April)
