Today, I was rejected from boarding after i checked in!! The reason was that my passport expires by the end of Jan 2012. I wonder why Tiger Airways accepted my online booking ticket even when I filled in my passport expiry date. In the first place, they should have just rejected my booking. Furthermore, they rejected me from boarding when I already checked in. My luggage was checked in and to retrieve my luggage, I had to proceed to the Arrivals hall. The items I bought from duty-free also had to be refunded. Throughout the whole process, I wasted a lot of waiting time.
