Aegean Miles+Bonus releases every few months a new set of “Happy Miles” that can save up to 30% off mileage award rates on select routes.
The latest batch is valid for travel between September 1 – November 30, 2017, on both Aegean and Olympic flights.
You can access Aegean’s web page for this offer here.
Here are the discounted routes:
Many use Aegean Miles+Bonus to get easy Star Alliance Gold status and are left with some redeemable miles to use as well. Could be worth spending some for these discounted flights, although they are all in economy.
You should check costs of paid flights as well. Some of these destinations are probably cheap and not worth redeeming.
