Alright then, I’ll ask the crystal ball holders here to weigh in on their guesses to the following (knowing nobody will know for sure)

I’ll be transiting BA 238 and 213 next summer from BOS to LHR and then return. A year out both are listed as 787-10, which I realize may not mean anything, but this summer and all in recent memory they have been a 777-200 and A380, respectively.

I’m not particularly preferential to any specific craft, just a curiosity, but I’m not sure BA will have the numbers of 787-10 by then. Thoughts?
