Government Bus 389 from Suvarnabhumi Airport is the gold standard for budget travelers. Departs hourly 6am-10pm from Level 1, Gate 8, costs exactly 143 THB (no haggling), journey time 2 hours. Most departures go to Jomtien Bus Station on Thepprasit Road, but the final 10pm service terminates at North Pattaya Bus Station on Sukhumvit Road instead. Buy tickets at the official counter—ignore anyone approaching you with 'special deals.'

Bell Travel Service offers premium comfort from Suvarnabhumi with 5-6 daily departures (first at 8:30am, last at 6:00pm) to Pattaya Bus Terminal on North Pattaya Road. Tickets cost 200-370 THB depending on seat type, journey time 90-120 minutes with toilet stops. Book at Bell Travel's official website or their ground floor counter near domestic arrivals.

U-Tapao Airport Strategy changes everything if you can fly there instead. Only 45 minutes to Pattaya versus 2+ hours from Suvarnabhumi. Airport shuttle costs 200 THB or legitimate metered taxis run 400-500 THB—dramatically cheaper than the 2,000+ THB taxi mafia at Suvarnabhumi.

Pro tip from years of train travel: those aggressive taxi touts at Suvarnabhumi disappear once you walk past them to the official transport counters. The buses are punctual, air-conditioned, and you'll pocket 1,800+ THB savings per trip. That's enough for three days of excellent street food in Pattaya.
