I looked up the miles earnings table on Aegean and it looks like some of the economy and discounted economy will count albiet at a 50% rate. Most of the United flights they book are W or L

Economy Class - Y - 150%
Economy Discounted - B, M, E, U, H, Q, V - 100%
Economy Discounted - W, S, T, L, K - 50%

Am I reading that correctly? If so, just one trip would land me at Blue and three trips to reach gold.
