Nok Air has started flight/road/ferry combo services through to:
The web-address is very (very ) long so have done a tinyurl to make it easier
Here is an example 7th Feb Bangkok to Koh Lanta:
Depart 0900 bus arrive pier 1000.
Dep pier 1230 arr Koh Lanta Saladan Pier 1430 ( Tigerline Ferries )
Fare inc all charges B 2,340
These are interesting new options with 'thru-ticketing' all in one go on the Nokair website
Also makes things easier for those heading to Langkawi in Malaysia not have to fuss about transfer farranging transfer to the pier, ferry tickets etc.
The Nok Air flight/road/ferry combo to Koh Samui seems to be doing well and I guess the reason behind the new services.
