The boat has been missed for LCY - the place is operating to capacity during peak hours. In fact LHR is a better experience during peak hours as a pax than LCY.
Poland perhaps but will that be seasonal? Still if it's cheaper out of EDI or PIK then these folks will travel by car/bus to get there. The number of Poles and Lithuanians that connected with Ryanair at LPL from ABZ was amazing when they operated the route. Cheapest option at the time to get to Eastern Europe!!
Rotterdam - bmi hold slots for RTM but they can't find the aircraft. With the large Shell presence that exists in RTM there could be enough pax to justify a little E135 on the route. Can't see VLM touching it since it would take forever and a day in a F50 and a RJ85 will have too much capacity if it is operated under the new VLM/CityJet agreement.
Emirates won't be coming - fact!
BA is in a stronger position with IAH since it has moved its flight from LGW to LHR so better connections for pax plus better facilities with T5 openeing. If there was ever a time when premium pax won't give up on BA from ABZ-LHR-IAH - its now! Citystar Executive - your days are numbered!
