Come in and clean up was a suggestion that EI could adopt routes not already operated from NI eg Gdansk, Riga, Lisbon, Budapest, Brussels, Frankfurt etc, maybe not all daily but certainly a couple of days a week. As for LHR BD have taken advantage of no competition with over inflated prices. I know a guy who recently travelled to Vancouver, Dub-Lhr (EI) then onto Van, it was over £200 cheaper than BHD-LHR then Van, this guy lived on the north side of Belfast.

People seem to underestimate the traffic from Belfast on the domestic front, its not far behind Gla/Edi when you combine both Belfast Airports, these services have been operating successfully for years only Lhr has declined over the past 6 years.
