At least EI seem to have loaded some fares, based on this routing:
Code:
SPECIFIED ROUTE: 0011
BRS-SNN/DUB-NYC
BRS-DUB-SNN-NYC
BRS-SNN-DUB-NYC
Lead in fare to NYC is £254 (plus tax), compared to CO's £241 and KL's £256.
Incidentally, with all this talk of (non alliance affiliated) EI operating BRS-DUB-NYC, let's not forget that you can still book BRS-BRU-NYC on the CO fare.
Code:
BRS(CO/SN)BRU-BOS/CLT/DTT/EWR/NYC/PHL/WAS(AC/CO/LH/UA)NYC
BRS(CO/SN)BRU-NYC
BRS(CO/SN)BRU-EWR/NYC(AC/CO/LH/UA)NYC
You have to call CO on the phone, and availability on the BRS-BRU route is really ridiculously tight (I think it books into SN's S or V classes), but it works and the connection at BRU is good in both directions. (I know that the crew who worked the final EWR-BRS went back on the Monday on this route).
