FlyBe
Great news! Finally some regional connectivity returning to Stansted. I was surprised when they sold the Gatwick slots that this wasn't done sooner. But such coverage of the London market, I would expect to see some consolidation of their London routes post the launch of services from Stansted.
This is exactly the start of what the airport needs to attract some longhaul carriers. After all do Etihad not have a code share agreement in place with FlyBe?
