bkk to koh phi phi, or krabi, or koh samui

And another question! How much is it to fly from bkk to koh samui? and how long is the flight?

Take a look at the bangkok air website. They are the only airline flying this toute. Notice that the first and last flight of the day is a bit cheaper than the rest.
For Krabi and Phi Phi you can look at airlines such as airasia and Nok as well into Krabi or Phuket airports .. they also fly to Surat Thani.. giving you a second option for Samui.. but you then have to take the ferry across.

That should have said.. Bagnkok air is the only airline flying Bangkok to Samui!

the flight from bkk to samui lasts 1 hour and 5 mins. bangkok air has flights there almost every hour.

cost me 3900 baht. booked online to.

thanks for the info you guys! i am going to be spending most of my time on koh samed island. is there anyways of not driving back to bkk, and then to one of the island? or will i have to go to bkk no matter what? thanks so much.

Koh Samet is to the east of bangkok and the other islands you mention are to the south.... You'll need to be a very good swimmer if you are going to be able to avoid going through Bangkok.
