A while back there was an offer posted here for a great deal on flights to Hong Kong with Oasis Airlines.
I managed to get the flights I wanted flying out on the 4th April (ie a few days ago) Unfortunately when I went to pay, we'd lost the flights. I rebooked for August - but cancelled a couple of hours later because I had asked if it was the rainy season and told it wasnt (and it is!) I managed to get a full refund.
Oasis has just gone bust. So I would either have been stranded now in Hong Kong - or lost all the money from the August trip!
