I'm curious about EI102/103. Early day time departure from JFK, arrive in DUB at 23:30 local was it? I'm guessing they are after business people looking to get a good night sleep in a hotel before doing a day's work in Europe, but it arrives way too late to get any connection with EI, and they're using a 757 with no sat broadband, unlike the Airbus, meaning these people can't do any work on the flight........
I would argue that they are targeting the Leinster region pax and the business pax who have meetings in NYC. The early arrival suits both markets and the pre-midnite return suits the former. The late arrival into DUB could also suit some MNC exec's with a full work day in Dublin the following day. Getting the Irish based pax out early also allows them to offer more seats to inbound transfer pax.
Personally I am happy to see EI trying this option. Frequency on a busy route is attractive for the higher yield pax.
And in relation to wi-fi on the B757's.....have a little patience.
