What's Delta doing?
They are still flying their 777LRs between Atlanta and Shanghai, Seoul and Tokyo.
And I am here to verify that at least this one passenger does indeed know what type of aircraft I fly, and is keenly interested in a final fix to this problem, beyond operational work-arounds to unclog the ice from the heat exchanger tube sheet. The 777 is my most frequently flown airframe (I keep a log).
Edit: I meant 777
ERs, not
LRs. The LRs have different engines and are used on other routes.
