OLTexpress
I can see their flights on radar (in Luxembourg) operating pretty well from Saarbrucken during last week to Vienna, Munich and Hamburg. There are no planned to flights to any of the London airports until next Easter, and as far as I can see it will be SEN, although negotations must continue between airline and airport managements. When Expressflight comes back from his holiday, maybe he will tell us more of what he knows. To start a Saarbrucken-London service this time of the year I believe would have lost them a lot of money, but once set up and promoted properly with a good times schedule, it can work.
