Here's what I've gathered for domestic widebody flights from LAX (using 7/1/21 as a data point):
LAX-MIA (5x 77W, 1x 772)
LAX-DFW (1x 789, 1x 77W, 1x 772)
LAX-ORD (1x 789)
LAX-JFK has now moved back to all 321T. Looks like the 1x daily widebody on LAX-PHL still hasn't returned to the schedule.
Have I missed any?
