We thought we were in for a hellish trip - just as we boarded, they told us that air traffic control systems in London had crashed, and we were looking at a three hour ground hold. Hmm - fortunately, that cleared in 45 minutes, and they made all but 20 minutes of that up in the air. That still left us with a 5+ hour layover - but good fortune again, we were able to get our bags switched to DCA, and put on standby - worst case - we get out for DCA at 6 instead of out for BWI at 8:15.
Unfortunately, WiFi here is really spotty - I had it last week down by K19 (weakly), but there's nothing here by K4. Sigh....
Missed that flight - waiting for the 6:00pm. And sitting on the floor outside the Admirals club, grabbing the tmoble hotspot :)
