Yeah you can be on the phone with the company travel department telling you the United flight at 10:13 doesn't fly between Dulles and New York on Tuesdays, and quickly type FLY IAD NYC<go> and you'll see a line like
12. UA 456 10:13 IAD 11:35 LGA vvvv vv
(Where the v's are checkmarks in day-of-week columns; so you know it flies every day but Thurs)
Then you type 12<go> and get all the details. It all happened as fast as you could type plus about 10msec plus the speed of light roundtrip to lower Manhattan. And in the nine years since I used it, I bet they added other points of presence on other continents.
