So I looked and found Mr.Rebates offers 1% Cashback for flights departing: Australia, China, France, Germany, Italy, Japan, India, New Zealand, Singapore, South Africa, Switzerland, UAE, UK and the US. (Tested on Ex- BKK and worked fine too - so will probably work for many other destinations) Since it covers quite a bit of major countries I thought I'll post it. If you want to sign up this is my referral ID: http://www.mrrebates.com?refid=554926 This is is legit unlike the corporate coupons P.S. Cashback posts 1 - 2 days after booking, instead of the usual which is after the flight has taken place. I've already gotten mine paid =) Cheers!
