Why limit yourself? Go as far as CHC or AKL and earn 45000 tier points (5K short of Skywards Gold) or more than 70K AS miles (more than 90K if you have higher tier status). All for less than 4K EUR.
But if you ask me, CAI always was a cheap origin for premium fares and this year we definitely saw better offers on this routes. Positioning to CAI might also not be a piece of cake for some of us. Unless you fly EK so often and therefore value the status with them, you could wait for a better offer.
