I'm wondering how many of you have been on a flight that has arrived before it left. For example on my trip back from Helsinki, Finland to San Francisco last Saturday, we left late, about 20 minutes behind schedule (about 1710 Helsinki local time) but the flight time, which is usually much longer than the trip over because of fighting the jet stream was shorter than the trip over, with a flight time of 9:22. The estimated flight time in the Finnair timetable lists a 10:40 flight time. Nevertheless, we arrived an hour ahead of schedule (throwing SFO into some sort of chaos I must admit) at 1630 San Francisco local time, literally arriving before departure. Some short flights (like HEL-ARN) regularly arrive 5 min. before departure (in local times of course) So if you have been on a flight like this, post a reply, be sure to include flight number, from where to where, and flight time.
