How can they be cheaper when Jetstar guarantee to beat by 10%?
I remember when flight centre used to have a similar deal (and I didn't have staff travel). I'd simply get a quote from flight centre. Get the other travel agents to beat it. Flight centre would knock 10% off. I'd then do the rounds again. Flight centre would keep knocking off 10% until no one would play the game with me.
Saved a lot of money until they changed the policy, and I got staff travel
