The 4 Day Sale has ended but you can still take advantage of the various offers here:
Or specifically for Indonesia, Thailand and Pakistan the buy one get on free on business class is still available:
Qatar Airways has a 4 Day sale offering some good value flights out of Singapore and the rest of the Asian region at up to 25% off the usual Economy and Business class flight prices. Travel is valid between 27 Oct 2013 to 19 Jun 2014. Qatar are also joining Oneworld from the 30th of October so maybe useful if you had some plans and want to stick with the alliance.
I checked out some random dates and came out with a return flight to London in Business for just over $S5000 which is very good value. You could also get to fly the new Dreamliner too!
It doesn’t look like the sale includes some of the shorthaul routes including: Flights between Denpasar/Bali and Singapore, Hanoi and Bangkok, Phnom Penh and Ho Chi Minh City, and Kuala Lumpur and Phuket. No flights out of Australia or Korea seem to be included either.
Blackout Dates are: – 18th – 23rd December 2013 and 2nd – 12th January 2014.
Travel into Doha as a final destination is not accepted either, unless from certain countries.
Here’s the link to the offers page, with the full terms and conditions:
From what I’ve been told they are a great airline, just wish I could use this sale period!
