When does something other than flying beat LHR–DUB?

Ryanair from Stansted or Gatwick can beat LHR cash — compare total door-to-door time from your London start point, not just headline fare.
See London airports compared when secondary-airport pricing diverges sharply.
Ferry plus train suits slow travel and car passengers — not business-day Dublin meetings from London.
