Not everyone using the train from Southend is terminating in Liverpool Street or Stratford for that matter. I’ve used the train to get to Southend Airport on a few occasions and it really is rather pleasant and hassle free experience.
LTNman I have to admit that through the years of knowing you on here you are somewhat obsessed with train and journey times to London, always trying to prove a point that your LTN airport is best positioned. Not everyone using London airports live or need to get to/from Charring Cross/Trafalgar Square. I honestly thought this was only something you bring up every year or so on the Stansted thread, however it seems you’re just as guilty of it here on the Southend one.
What exactly is it that you’re trying the prove on here? You really should consider a career within Luton airport’s marketing team.
