I know we were all upset when jetBlue disabled the flightview software from the new web site. However, I noticed a thread about this on a.net. JetBlue has added a pretty cool feature. Track a flight this is currently airborne and click "view map" under status.....

***In the above link I randomly chosoe JFK-LGB for today. If there are no current flights in the air, just track a different city and repeat the process to see the live, interactive map!
