A few years ago I was flying as pax back from Budapest to LHR, and overheard this between the American couple seated behind me and CC:
pax: Sir, when we flew from London to Budapest we took off at 12 and arrived at 3pm - but now on the way back we took off at 10am and the captain just announced we will land at 11am. Why is it shorter today?
Obviously busy CC: This pilot knows a short cut, sir!
American woman to husband: Oh, good for him, honey - aren't we lucky today!
