I need to locate one of those for a SYD-Moscow!
But yes, in the past I have found using the 10% an 20% off Certs that they often throw up a silly message saying
"valid coupon but no available flights" or somesuch nonsense, when there is no issue at all with "valid flights".
Using the 10% off ones if I apply it to a SYD-IAD it takes, but SYD-EZE via IAD it does not for same dates .. .etc, despite that being perfectly valid use.
