My experiences with Tiger Airways:
1. I was among the thousands of TR passengers stranded when Yellow Shirts closed BKK airport Dec 2009. Tiger abandoned all of its passengers. All Tiger did was to offer "full refunds" and "advised" their stranded passengers to seek free hotel accommodation from the Tourism of Thailand. Thai Air Asia's aircraft were inoperable, caught in the BKK airport siege. Only Jetstar launched rescue flights into Utapao airport (Pattaya) to get their stranded passengers out. I will never forget the good deed from Jetstar. (Tiger is the typical fairweather friend.)
2. Tiger cancelled several flights out of Singapore when they had some problems with their pilots in 2010. I was waiting in line at the budget terminal waiting to check-in when the announcement of cancellation was made. Tigers offered me a full refund as their "gesture of goodwill". Yuh, right!
3. I paid US$10 to TR for my 9 Kg check-in bag since it exceeded the 7Kg allowed for carry-ons at Clark airport (Philippines). On arrival SIN airport I found the zipper of the bag damaged. TR gave me a form to complete and mail-in. A photo of the damaged bag had to be submitted with the claim form. After waiting 4 weeks and several calls, TR denied my claim for S$49 (US$26).
