You have to have a common point of reference for speeds, otherwise comparisons are meaningless. It is implicit in a "speed of sound" statement that we are measuring with respect to the fluid that is transmitting a hypothetical sound.

If you want, you can say that a plane sitting on the tarmac is travelling at 1000 mph, because that is how fast the Earth is rotating (at its equator). Or I am travelling at 515,000 mph because that is how fast the solar system orbits the centre of the galaxy. But that none means I am travelling faster than the speed of sound.

I also had an unusually fast LHR - BOS once when the usual headwind was a tailwind - again, I don't remember the numbers.
If this was late August/Early September then very possibly.^

Fast flying

The seat TV screen on BA214 BOS-LHR last night showed 739 mph just east of St Johns. Not a night to try the soup. The speed of sound is 761 mph. Would the pilot have had to keep below the sound barrier?

Have a look at this recent thread which discusses the same BAW = Callsign Speedbird - Literally.

Unfortunately you weren't actually close to the speed of sound.

Looks like some fast W-E TATL flights tonight - 150 knot tail winds mid-Atlantic - with flights booked to arrive >1 hour early!

Several BA pilots tweeted their flight times, which were quite impressive. There was a DFW LHR just above 7:30 flight time.
I am flying from IAH tonight and it is expected to be as fast (and apparently bumpy too).

Last night's BA275 (LHR-LAS) departed 1hr 6 mins late and arrived 4 minutes early!

I wonder whether this is to do with the (ex-)hurricanes that are crossing the Atlantic at the moment; Lee first, followed by Maria.

Indeed - both Maria and Lee have been swanning around doing nothing for a while (as did Jose), then suddenly being picked up in the jet stream.

As others note - bumpy ride in store for all - but quick!

As expected this was fast: 8h30 to do the jump IAH-FRA. Smooth as well, except for some light turbulences when we entered the stream above Washington.

Doing some Googling, it seems the record is this one:

Jet stream blasts BA plane across Atlantic in record time - Telegraph

So 745 MPH, not 720 = ) And 5 hours 15 mins JFK-LHR!
The Telegraph are keeping an eye on things:

BA loses transatlantic time record to Norwegian thanks to ferocious jet stream

Stealing their passengers and stealing their time records... Soon they'll have T5.
