As that flight AY5415 is a codeshare flight operated by British Airways, please ask this question in the BA forum for better answer.
Finnair doesn't have 777's and nor do their metal fly between LHR and BOS.
It's
AY5413 actually and both the Airport website as Finnair state they do fly from Heathrow to Boston, so I think you are in the wrong.
Google on: "AY5413 Finnair", for example.
I could be wrong too, but then this is very confusing.
