Here is the Bell web site.
The Bell Bus leaves the airport on even hours.
The Jomtien Bus leaves on odd hours. It also will drop you off on Sukhumvit at Pattaya Klang or Pattaya Nua.
So lets say one is staying at the Mosaik or LK Pavillion which I know are favorites of many board members. You buy your ticket for 124 baht on the ground floor at Gate 8 which is right next to the lowest price food court I^ve ever seen at any airport.
Get off at Sukhumvit and Pattaya Tai and then cross on the overpass to the beach side of Sukhumvit. On Pattaya Tai there is a queue of baht buses which leaves when filled but the wait is only a few minutes cause there^s a big shopping mall nearby. Get off at TukCom and pay 10 baht, total trip 134 baht.

Note there is a 19:00 bus though it^s not listed on the website, I know cause I^ve taken it twice. The bus is actually roomier than the Bell Bus.
