As Fletch stated. I will add to what was stated noting the line by the luggage recheck does not have Precheck and can be long and slow, and if you have Precheck or Clear and are in a hurry we have found that if we exit that area to the general population up to the ticket counter area you can save time. If you do this when you exit you go up to the ticket counter area and go one station to the left (if facing the ticket counters) and you will find Clear and Precheck. We have done this three times now, and will do the next time even if we have time to wait. Prefer going through with Clear and Precheck, we have both.

I prefer the Isle seat
