johnnychips,
Whilst ignoring the juvenile(s) at least, were I to live around Plymouth, I could fly out on a breakfast time flight and, via a connection, be at a European destination by lunchtime and I'd be able to catch an evening flight back to Devon.
Exeter or Newquay, breakfast time flights out of the question, no public transport unless hotel the night before, evening flights back then difficult if any public transport and not in bed until midnight or later.
