Anyone experienced this and help???

Select the country first before input your ZIP code, will help

已試過你的方法，唔得
最慘剛過ｐｒｏｍｏｔｅ，打電話去又聽音樂，真係出煙
請問有冇網上訂過機票，有否同樣問題？

I have online purchase tickets twice on Tiger website, input "000000" in Zip code field

Postal code thing really piss me off. I called GuangZhou office eventually which charged me full fare. Slightly expensive but still cheaper than other options.
Since then I am thinking to Kuala Lumpar, when return as hub, by Airasia which cost similar but less booking trouble.
