Bear in mind that both Jetisfaction and OLT would have suffered the same difficulties in brand recognition had they flown from any other London airport; it is more a matter of start-up carries facing certain difficulties relating to their embryonic nature rather than the airports they choose to fly from. So I wouldn't blame SEN for their problems - Aer Lingus and easyJet have had an easier time because they are household names; Jetisfaction and OLT Express Germany, with all due respect, are not.
