Both Flybe and Aer Lingus have filed slot requests with the German slot-coordinator for flights from DUS to LGW with the E195 and the A320 respectively. EI is only a once-daily midday service, so LGW might be just a dummy for something else (BFS?). Because of the scarcity of slots at DUS, none of the requests has been met so far.
Would be nice to get back a DUS route from LGW. The route has a long tradition and was served by BCal Commuter, Air Europe, Cityflyer etc. A while ago there were flights from DUS/MGL to LHR, LCY, STN, LGW and LTN by seven airlines, now we are down to four airlines, no service to LTN and LGW and STN facing a downgrade to the 78-seat DHC8-Q400 in 2009.
