You've now asked about the shortest flight from New York to continental/mainland Europe. NYC to Lisbon, Portugal takes from 6h 50m NYC to Madrid, Spain takes from 7h 6m. There are several other places with only a little longer flight time from NYC e.g. Brussels from 7h 10m, Paris from 7h 15m. Note that there's no absolute certainty about flight times: tailwinds can make transatlantic flights faster (my US>UK flight landed 30 minutes early just 4 weeks ago), headwinds can slow flights down, airport congestion can cause delays in take off and/or landing.
I assume you mean direct flights from Boston? Do you mean 'Europe' the whole continent, 'Europe' just the continental mainland, 'Europe' the EU, 'Europe' the EEA (European Economic Area) or 'Europe' the Schengen Area? The whole continent, the EEA and the Schengen Area? Reykjavik, Iceland. (5h 15m from Boston) The whole continent and the EU? Dublin, Republic of Ireland. (6h 10m) The continental mainland, the EU and the Schengen Area? Paris (6h 40m)
Stevee Hi Mary - I'm looking for the shortest route from the US to continental Europe, by air. Would it be NYC to Madrid??? Thanks, Stevee
Mary Hi. Your post wasn't very clear, hence my first reply. For the shortest route from NYC have a look at my second reply. It's not Madrid.
