U.S. departures add a second border after CATSA. Official CBP Winnipeg preclearance hours are 05:00–18:00. Neither lounge is on the U.S. side of that door.

A short domestic CATSA wait does not help a Minneapolis or Chicago itinerary. After U.S. check-in, follow the transborder signs between Door 1 and Door 2, cross the bridge, then clear CBP. Evening U.S. metal still has to be processed before 18:00 — and the holdroom food is Urban Crave only.

One 2011 building, two products. Domestic and non-U.S. international share the Door 3 CATSA hall; U.S. flights use a separate checkpoint and CBP pier. Connecting Canada→U.S. is a landside bag reclaim, not a stroll.

Official WAA connecting page: leave the domestic/international gate area down to Arrivals, collect bags, go back to Departures Level 2, then transborder screening + preclearance. Perimeter Aviation is a different building 2.6 km south — do not walk it with a jet boarding pass.

Density is in the domestic/international hall (Starbucks, Prairie Bistro, True Burger, Little Brown Jug, Freshii, Booster Juice). After CBP the official directory lists Urban Crave only.

Sapphire Lounge on the official dining list is a public bar with cold plates — not a Chase Sapphire Lounge and not a Priority Pass room. Trust today’s what’s-open board; WAA hours drift between the directory list and the vendor pages.

Live Priority Pass Canada includes Winnipeg. The pin is Plaza Premium opposite Gate 6, 04:00–21:00, max 2 hours. It is explicitly not accessible on U.S. transborder flights.

Maple Leaf opposite Gate 9 is Air Canada / Star only and also excludes U.S. departures from Winnipeg. Do not invent a transborder lounge, a Centurion, or a Chase Sapphire Lounge by The Club. Door 2 is closed — U.S. screening is still the Door 1–2 bridge.
