Just a word of caution about the IAD-LAX route. The scheduling of widebodies on that route is the most undependable I know of. I assume the IAD-LAX 772 part is on that ~5:30pm flight. The schedule may show a 772 now, but it is just as likely to be a 763, 757 or Airbus by September, and the suite goes bye-bye. It used to be one of my favorite flights, and the first route I ever flew the 777 on back in the 90s. Now it is hit and miss at best.
