I think I understand now why every other flight search engine has little "to" and "from" boxes. I got the "couldn't parse this" screen four times in a row trying to get from my house in Northern England to Kalymnos, Greece. It finally gave me results when I tried "manchester to kos", with the minor problem that all the results started in Boston, 3000 miles from my house. I like the idea. At the moment though the execution is simply not there.
