A bit risky but you could try US who will be flying to DUB startng 4 May (DUB-PHL-DTW). Assuming there is one running, you sign up for a challenge allowing you to earn status for flying 1/4 of the usual miles in a quarter (for Gold or Silver Preferred only), It's very possible to upgrade using miles or systemwide upgrades in the past (V fares excluded in recent years).

I'm not up to date on the most recent changes so check the US forum.
