There was another website which had a couple but I can't find it right now but will keep looking.
Reviews of London Southend airport (SEN)
Review submitted by Magnus Knight on 27/09/12, vote ********** (1)
As an ex-pat I had the misfortune to get diverted to Southend from London City. We had to sit on the aircraft for what seemed like hours as the airport did not have any staff to offload the passengers and luggage. I elected to catch a train to London instead of catching a coach that was laid on. BIG MISTAKE. The train was dirty old commuter stock and stopped at every station as it made slow progress to London. Hopefully I will never have to use this airport again and why it thinks it is a London Airport when it is so far from the big smoke is a mystery to me.
