Hi

I just discovered an oddity that I was unaware of. I wanted to search for flights from Nice to London on DEC24. I first did a NCE-LHR search and was quoted €109 for the particular flight I was looking for on ba.com. Out of curiosity i tried NCE-LON and the LGW flights appeared. So far, so good. The interesting thing was that the same flight to LHR was now priced at €98 (the LGW flights were all cheaper than the LHR flights)

Is this something new or is it just a "well known secret"?
