Application rules for Connecting flights
Hi all,
Coming back to the use of the coupons for connecting flights. This is the response I received from Customer Service.
"You may use your coupons for upgrade when the stock ticket number is ours[390/050]. In addition, when one reservation contains two or more segments, pure Aegean or Olympic flight, then you need to upgrade all flights, so as to use your coupons. "
So, it seems what I interpreted from the Wiki is correct. It's a pity though especially if you want to optimize it's usage.
Cheers!
