I've gotten an excellent rate using A286000 to rent from YYZ. Apparently, it's Air Canada (corporate?) I'm signed up for fastbreak, and in the page for my reservation it says: "As a Budget Fastbreak member, you’re all set with Budget Digital Check-in."

How risky is this? Has anyone ever been asked for validation of their BCD codes at YYZ when using fastbreak? Do i even interact with a human at the counter with this setup?
