This was a Norwegian flight...
They have subbed their MCO ORD DEN MIA and the early a.m. JFK flights out of LGW all this summer to Wamos Hi Fly Privilige style and Evelop Airlines for many flights due to ongoing 787 problems
The a/c types include A330-300/200, 777 and A340-300
I have been Evelop'ed from my 787 on the JFK-LGW this month to an ex SQ A330-300
