Yyz checking time for us bound flight
 

Looking for advice on when to arrive at pearson. We are leaving with Delta on Friday March 14. It's the end of the march break, not the start. Our flight is at 7:30 in the morning and we will have a couple of bags to check.

Do you have NEXUS/GE, status?
Are you planning to OLCI?
I typically do 1.5 to 2 hours before and have ample time.
The process itself should only take 1/2 an hour at most BUT boarding starts a bit early.

Assuming you don´t have NEXUS/GE and don´t have access to the priority lines, I´d recommend arriving at least 1.5h beforehand, 2h if you want to play it safe.

Do you have priority status with Delta? If not two hours might not be enough due to the long lineup to get baggage tagged and boarding passes that I usually see at DL check-in in the morning.
I fly out in the mornings with DL from YYZ T3 about 30/40 time per year. Even with priority check-in and security screening plus Nexus/GE my usual margin is 75 minutes.

We don't have a nexus pass or priority checking. Staying at a park and fly and the shuttle leaves ever hour on the hour, so 5:00 it is
