I'm flying out of YYC in a couple weeks - will check it out.

I feel like centralized screening is a nice idea, but a real pain in real life. My biggest issue is walking distances. Since YYC gave up on splitting Westjet at the A gates, AC at C, and the rest in between, its not unusual to have AC flights leaving from the far A gates. So now, you'll have to go through security near the B gates, walk back to the C gates for the MLL, and then all the way back across to the A gates for your flight. Heck, A15 - one of the furthest A gates - seems to always get AC's shortest flight out of YYC (to YEG). And in all my years of flying, I've never seen all the walkways in YYC working at the same time, so it can be a hike.

Meanwhile Westjet's lounge is next to this new centralized security area, so I guess its a nice perk for them. The old B security area next to it didn't have a verified traveler lane, nor did the A security area near Westjet's ground gates.

I don't have much faith in the folks that plan YYC. Let's be fair, this is the airport that regularly has the longest domestic connection distances in the country (D/E swing to A), and made a whole new terminal with virtually no seating for its TB/Intl gates.
