How many minutes of Air train ride is from long term parking lot to jet blue?

20 minutes

After parking in long term, 10 minutes max to walk Air train. Once you reach the platform. Every 5 minutes you get train goes via terminal 1,2...... 8. The max round trip time 20mintues to reach terminal 8. So all together 30 minutes you going spend after parking.

It's a 5 -10 ride I got there 2hrs before my JetBlue flight had no issues and they took is right away

About 5 to 7 minutes, but arrive 3 to 4 hours before your flights departs! If you arrive an hour before, they won't take you!
