Ua: DUB-DTW ~$1350 rt/j
 

Valid from 9 APR to 10 MAY. 7 day min stay. Tickets must be issued before APR 3. Fare basis: PLNCZ7E

There is another fare valid from JUN 25 to AUG 22 for a few hundred more with a fare basis: PLNCIEW

It appears in general that fares originating DUB to the USA are much cheaper than flying ex USA. I noticed recently that there were some DUB-East Coast F fares on EK for roughly $6k, while flights ex USA are often in the $15K range roundtrip on Emirates in F.

Wish UA would attack another Delta hub... like SEA, their prices to SFO are more than OW for Biz...

Fares also good to MSP, ATL, CLT, ORD, and PHL. A bit odd to include your own hub in the mix. BOS, NYC, and a passel of Florida cities are even less and available from $1222 - $1286.
