If you haven’t been to YUL lately, you’re in for a shock. The old "show up two hours early" rule? Forget it. Honestly, it’s a recipe for a missed flight and a very expensive afternoon spent staring at a departure board in tears.
Montreal Pierre Elliott Trudeau departures have become a bit of a localized gauntlet. Between the massive $7-billion-plus infrastructure overhaul and the sheer volume of people trying to escape the city, the airport is basically a construction zone that occasionally launches planes. It’s messy. It’s loud. But if you know the workarounds, you can still make it to your gate without losing your mind.
The Traffic Nightmare You Didn't See Coming
Getting to the terminal is half the battle right now. Because the main multi-level parking garage is being demolished and rebuilt, the "standard" drop-off zones are often paralyzed. I've seen people literally jumping out of Ubers on the highway and walking the final kilometer with their rolling suitcases because the road network is that backed up.
Basically, the airport wasn't built for 22 million people, and it shows. The ADM (Aéroports de Montréal) is currently reconfiguring the entire approach road system to stop it from backing up onto Highway 20. Until that’s done, do yourself a favor: use the "Express Drop-offs." They’re located further away from the terminal, but they have dedicated shuttles that bypass the main traffic jam. It feels counterintuitive to go further away to get there faster, but it works.
Your Secret Weapon: YUL Express
If you take nothing else away from this, remember YUL Express. It’s a free service that lets you book a specific time slot to go through security. You can do this up to 72 hours before your flight.

- Go to the YUL website.
- Pick your flight and a time.
- Show the QR code at the priority line.
It is a total game-changer. While everyone else is shuffling in a 45-minute snake-line at Checkpoint A, you just walk right up. Note that if your flight gets delayed, the system won't automatically move your appointment. You'll have to manually update it if you want to keep that priority spot. Also, it’s only for domestic and international departures (Checkpoint A) and U.S. flights (Checkpoint C).
The U.S. Pre-clearance Shuffle
Flying to the States from Montreal is a specific kind of stress. Since you clear U.S. Customs before you leave (pre-clearance), you’re effectively entering the U.S. while still standing on Quebec soil.
The lines at Checkpoint C can be brutal. If you don't have NEXUS or Global Entry, download the Mobile Passport Control (MPC) app. It’s free. You upload your photo and declaration while you’re standing in line, and it gives you access to a dedicated queue that is almost always faster than the general line.
Seriously, why more people don't use MPC is a mystery to me. It’s like having a VIP pass that you didn't have to pay for.

The Three-Hour Rule is Real Now
A lot of people think the "arrive 3 hours early" advice is just the airport covering its butt. In 2026, it's actually factual. If you’re checking a bag, you need that time.
The baggage handling system is also undergoing upgrades because, frankly, the old one couldn't keep up. If you’re flying Air Canada or WestJet, use the self-service kiosks to tag your own bags. It saves a significant amount of time, but the lines to actually drop the bag onto the belt can still be a slog.
Where to Eat (and Where to Avoid)
Once you’re through security, the vibe shifts. The international jetty is actually quite nice, with a lot of natural light and some decent art.
Food-wise, it’s hit or miss. If you're in the domestic area and want something that isn't a sad sandwich, Auberge Saint-Gabriel is usually the best bet for a proper meal. For a quick caffeine hit, the Starbucks lines are always a disaster—try the smaller local kiosks instead. They're faster and the coffee is usually better anyway.

One weird thing about YUL: some parts of the terminal get surprisingly warm. The HVAC system is clearly struggling with the ongoing construction and the record-breaking passenger numbers. Dress in layers. You might be freezing on the tarmac but sweating while waiting for your Montreal Pierre Elliott Trudeau departures gate to open.
Actionable Steps for a Smooth Departure
Stop winging it. If you want to actually enjoy your flight, follow this checklist:
- Book YUL Express 72 hours out. This is non-negotiable for anyone who hates lines.
- Check the parking status online. If you plan on driving, reserve a spot weeks in advance. The demolition of the old garage means spots are at a premium.
- Download the MPC App for U.S. trips. Do it before you leave the house.
- Use the 747 Bus or the REM (if it's finally running for your area). Avoid the car traffic altogether if you can.
- Track your flight via SMS. Text your flight number to 23636. The airport will text you if your gate changes or if there’s a delay of more than 10 minutes.
The "Flight Plan 2028-2035" means the airport is going to be a bit of a mess for a while. The goal is a shiny new satellite jetty and a capacity for 35 million people, but we're in the "ugly" phase of that transformation right now. Arrive early, use the apps, and maybe bring a portable fan. You’ve got this.
