How long would a flight between London and Cleveland take

How long would a flight between London and Cleveland take?
I have checked lots of airline sites but seem to get no answer. Never sure if it is giving me an answer with or without time difference. Also these times are odd. Are they all not calculated with time difference or what? I don't get it! 09:55 AM LHR 02:25 PM DFW 05:20 PM DFW 08:50 PM CLE Thanks, Dave xx

The time scheduled next the the airport code is the local time at that area. So it's 09:55 at LHR for takeoff, 02:25 arrival time at DFW, 05:20 at DFW for departure and arrival time at CLE is 08:50. Please use 24 hour code instead of attaching a AM or PM. If you're adding that zero before, as well as adding AM or PM, it can confuse a lot of people. I almost mistaken 08:50 for AM, state it like 20:50. Dallas is 6 hours behind London, so the flight duration between London and Dallas will be 10 hours.

When you look on line, the site gives you the travel time in hours as well.
