The Dubai venture may prove a nice wild card by rightly adressing
-the UK regional market of connections and sixth-liberty tickets sales, I think they are probably a lot of UK citizens working in the UAE who would enjoy a departure/return from/to local airport, if one of the many served by EI, then connect at far less congestion Collingston instead of connecting thru LGW, LHR or driving up or down to either MAN, BHX, GLA.
-the Irish market, by trailing the British, many Irish people work overseas. Should EI plans flying to DXB, some items of their market reseached confirmed presence of many Irish working in the oil industry.
