Prakorb Panyawai said everything would be in place for the low-cost, hop-on, hop-off service to begin.
''There won't be any fanfare or hoopla,'' he told Phuketwan today. ''We will simply start the service a bit later than normal because 9am is the appropriate time.''
No invitations have gone to Phuket administrators but the media was welcome at Phuket International Airport for the launch, he said.
The bus service will make Phuket history because the popular holiday destination has never before had a public bus service to the west coast as an alternative to high-cost airport taxis and limousines.
Eventually the service will be extended to neighboring Karon and Kata beaches and then further south.
No special security is being implemented for the bus service because there has been no indication that safeguards are necessary.
The service already has an online site, phuketairportbusexpress.com, where fares and a route map and other details can be found.
Initially there will be five stops but Khun Prakorb said this could grow to nine once the service developed a following.
Most tourists are expected to continue to take taxis and limousines on arrival on Phuket.
Although the buses were previously used at Bangkok's Sucvarnabhumi Airport and have luggage racks for large bags, many of the passengers are expected to be locals making short trips.
The introduction of the buses is part of a range of reforms that have been gradually taking place on Phuket under the Phuket Land Transport Director Terayoot Prasertphol and project specialist Jaturong Keawkasisaid.
As well as the bus service, Phuket's taxis have been formally registered and efforts are now being made to do the same with motorcycle taxis.
Yet to come is the extension of the Airport-Patong-Airport bus service to Kata-Karon, where taxi and tuk-tuk drivers have resisted the move.
A date has yet to be set for a public meeting in support of the extension of the service, but Khun Jaturong believes it will happen eventually.
The buses will roll from 8.15am daily beginning at both the airport and in Patong and there will be nine or 10 rounds per day.
Initially the stops will be at Thalang Council Offices, the Heroines Monument, Tesco Lotus intersection in Phuket City, and JJ Mal,l behind the Jungceylon shopping complex.
The sliding scale of fares is available from the online site. Taxis are expected to continue to be the preferred option for people who wish to get to their destination speedily.
Encouraging Phuket residents to exchange convenient yet dangerous motorcycles for the all-weather comfort and safety of the Airport Express buses will be a long-term marketing exercise.
