@AirlineReporter This is indeed a tricky view. At first glance I would have thought 787 like the other responses. The raked wingtip and position of the flaperon look like a 2nd generation 777, either 777-200LR or 777-300ER.
@AirlineReporter When I saw the raked wingtips, 767 didn't even come to mind. I forgot it got one last update in the 400ER. I only thought of 787 and 777. So I didn't try finding photos of it to compare.
