How to book your spot in the security line for free.

The YUL Express Line allows you to book a reserved spot in the security queue, saving significant time during airport processing.
The Express Line is a reserved security lane available at certain times. You book a specific 30-minute window for security screening. Your spot is held even if airport traffic is heavy.
Visit the YUL Airport website's Express Line portal. Select your flight date and preferred time slot. Confirm booking with your booking reference and flight number. You'll receive a confirmation email with your time slot.
Booking is completely free for most passengers. YUL offers this service as a passenger convenience. Some frequent flyer programs include automatic Express Line access.
Express Line reduces security wait times to 5-10 minutes during peak hours, compared to 30-60 minute wait times in regular lines. The savings is substantial, especially during summer and holiday travel.
Busiest times are 6-8 AM for morning departures and 2-4 PM for afternoon flights. Weekend travel also sees longer queues. Book Express Line during these times for maximum benefit.
You must arrive at least 30 minutes before your reserved slot. Bring all required documents. Arrive early enough to handle any unexpected delays.
