How long is a flight from New York to London?

 6 hours 50 minutes.

My wife was telling me that they likely do a polar flight even from new york to London like they do from San Francisco to London which is 11 hours and 16 minutes.

I have made the flight from San Francisco to London twice, once in 1999 and once in 2011.

I have also gone to Paris via Amsterdam which is another Air hub in Europe like London is.
