VfW614, actually you forgot OLT`s Do 328. I admit, currently they couldn´t deploy it on such a run, the plane is attched to the BRE-TLS flight and is in TLS all day long. The only way would be aquiring a second one, something which is not out of question since they want to standarize their fleet. The Saab isn´t possible at the moment, too, since it is dedicated to the ERF-MUC segment. All three Metroliners are busy, no chance to add London-flights. Every kind of expansation will mean adding at least one more plane to the fleet. But hey, thanks for your opinion, was interesting to read!
