Flywatch
If I lived in the Southend area and wanted to go to Ostend or Calais with family or friends I think I'd definately drive to Dover or Ramsgate and catch the ferry or go through the tunnel rather than pay £200 each! However, I'd fly from Glasgow or Prestwick to Ostend if it was possible as I go there several times per year. The chanced of being able to fly from Glasgow or Prestwick to Ostend are nil and anyway, I still wouldn't pay Flywatch fares!
