I noticed that my DPS-BKK seat map for my flight in late May has changed. The map originally reflected a 773 (non-ER) with 2-3-2 angle-flat configuration. Now, though, it has the staggered 1-2-1 usually found on 77W, but it also shows it with 2 J cabins as well. Any idea if I am now flying a 77W that has a bigger cabin, or a retrofitted 773? And I assume I now have full lie-flat instead of angle flat too
