I'm trying to decide where to put my miles into . I'm new to this and have just started earning frequent flyer miles for Aegean air Miles and Bonus program. But the only reason I put them in their is because of the access to lounges . ( if there is an easier way , let me know ) .

Aside from that , I don't know where to put my miles. I frequently travel to Asia from the US. I don't travel much domestically in the US. I was thinking of United for a bit but after the announcement of the devaluation of the miles, I'm not sure. It doesn't even have to be Star alliance, just which frequent flyer program should I put my miles in ?
