Dear K.Pream,
I checked with the airline for SHEVCHENKO’s ticket already. This ticket validly for 3 months only. So the last date for departure from Bangkok is Nov 03rd ,2015 only. If you like to change flight to Nov 03rd you must to pay the fee THB 4,000 (Price guarantee day by day and depend on available seat.) you must to pay the fee soon as soon possible because the price can change all the time depend on the available seat. If you need to change please confirm back to me again.
