Sea Air
Don't know whether I'm reading their site correctly but it now looks like Sea Air is threatening to start Munich flights next Wednesday, 29th June. Let's wait and see.
Re the National Express coach, I also wonder how it's doing. I only live 10/15 minutes walk from SEN but have no intention of trotting up there at either 05:00 or 23:30 to take a look. I somehow doubt that it is doing much but assume it will carry on as long as Stobart continues to subsidise it.
