While doing random searches for flights from JFK-LHR on Kayak.com, I came up with a BA option leaving from EWR. It appears that BA #186 (EWR-LHR) and #187 (LHR-EWR) are operated by the 767. I thought that was interesting, considering that a 767 also operates the JFK-MAN service.
Does anybody have any other info. regarding this change? I'd be curious to know.
Have a great day everyone!
