We would like to do a quick trip to Siem Reap. We will be in Bangkok and Phuket.
Questions:
1. Does the Phuket-BKK-Siem Reap-BKK count as three legs?
We need to end up in BKK. But thought we could use a leg to get from BKK-Phuket if we needed an addiotnal leg.

I know this is totally confusing. Can anyone help me?

yes, you have three legs listed:

Puket-BKK
BKK-SR
SR-BKK

yes ad cost would be about $210..

s/b "and cost..."

I think you canb get this pass with more than 3 legs if that helps.

yes, you can get as many legs as you want i believe...

minimum three legs and maximum six. Domestic legs are $50 and international legs - as in going to Siem Reap - are $80.
