Flight TCX12L Sanford Orlando (KSFB) to Belfast (EGAA)

I travelled on this flight on August 14th and because I have travelled the same route many times before was puzzled by the overland track that it followed as opposed to the usual one which is normally northwards along the Eastern seaboard before heading across the North Atlantic. Anyone got any ideas why this should be ?

Thanks.

A link would be nice.

Probably favorable winds.
