Why Paris first

  2. Paris to Barcelona$37
  3. Barcelona to London$19
  4. London to New York$322
  • Out of New York, Paris is the cheapest first stop at about $229. Barcelona would be $270.
  • Going home, the cheapest flight leaves from Barcelona at about $318, but the cheapest order ends in London at $322 because the rest of the route is cheaper that way.
  • The dearest order pays $353 for Paris to New York, a flight the cheapest order never takes.
  • London to New York is 53% of what the cheapest order spends on flights, so it is the leg to watch.

Between the cities

  • Paris to Barcelona: about 830 km (520 miles) as the crow flies. Also by ground: TGV, about 6h 40m, usually $50 to $150.
  • Barcelona to London: about 1,140 km (710 miles) as the crow flies. No train or bus we would suggest instead of flying.
