Carlisle-Euston takes 3h25m on a train which runs every hour. Carlisle is not a huge city and is surrounded by large swathes of countryside with 2 large national parks nearby. May I ask what the proposed customer base is for this new CAX-SEN route ?
davidjohnson6 - Let's also look at it the other way round. Southend to London's an hour by train; crossing London to Euston takes the best part of another hour. People from Essex travelling to The Lake District, Northumberland, and the Cumbria/Lancashire M6 corridor, as well as South West Scotland and the Borders could use this flight and avoid adding to the congestion of London in rush hour.
