WWW the fares for the next 2 weeks or so are high, maybe this is because the flights are extremely well booked and the cheap fares are no longer available??
I agree on US knowledge of the area though - maybe an idea for the South-West to get themsleves over to US and not just EWR to shout a bit louder on the subject. Also it is not just US that need a bit of help - many in the south west are aware of BRS-EWR but still believe that they have to go to LHR/LGW for anywhere else west of Dublin
