the new Terminal (T3) has jetbridges, so everyone boards the same way, but for CO they still have the Blue EA carpet.

BF pax usually get out first, there is no special line, and its never been a long wait (never more than 5 minutes, often about 30 seconds).

The BF checkin(+ security interview) line is on the far left side. There is no F security line in TLV for the metal detector/x-ray, but again, its never been more than a couple minute wait.
