Historical Flight Number Needed

Hello,

I am looking for the flight number for a flight from Heathrow airport to JFK airport on December 12, 2002. If anyone could please help it would be greatly appreciated. I believe the airline was British Airlines, but I’m not 100% sure. I have tried numerous times to search but could not find anything.

Thank you,

Kasia

There’s more than a dozen daily flights on that route, can you be any more specific?
