What happens if I arrive at the priority line earlier or later than the time I booked?

You are allowed to arrive up to 15 minutes before or after the time of your booking. 

 If you arrive earlier, you will be directed to the regular line at security checkpoints. We recommend that you wait until the time of your reservation before heading to the priority line at the security checkpoints.

If you arrive later than 15 minutes after your booking time, you will be directed to the regular line at security checkpoints.
