Connections at YYC: the honest numbers
The indicative minimum international-to-international connection at Calgary is 75 minutes on a single booking with bags checked through. On separate tickets, add roughly 90 minutes: you'll collect bags, recheck them, and re-clear security — and no airline is obliged to help if the first leg runs late.
Transfer specifics
- Calgary runs two connected terminals across five concourses. Domestic uses A1, A2, B and C; Concourse D handles non-US international and Concourse E is exclusively US-bound with preclearance. A 620-metre walkway links the two buildings, served by the free YYC LINK — a fleet of small electric shuttles running airside. Walking between the farthest gates takes about ten minutes; the shuttle cuts it to roughly three.
- Canada, unlike the United States, has a genuine transit area — so an international-to-international connection can stay airside. But you still clear Canadian Immigration, with separate counters for transiting passengers. Domestic-to-domestic connections involve no checkpoints at all; just find your gate.
- The thing that catches people at Calgary is the US preclearance metering. CBP operates on Concourse E daily from about 4:30am to 8:00pm, and access to US security and CBP is metered at two hours before scheduled departure — arriving earlier will not get you through, with exceptions for travellers with mobility aids, families with small children and accessibility needs. Late-evening US flights after 8pm do not get preclearance at all. YYC encourages US-bound passengers to file a declaration via the Mobile Passport Control app before arriving to speed the queue.
- Canada requires an eTA even for transit for visa-exempt passports including Australia, New Zealand, the UK and most of the EU; US citizens are exempt. It costs CAD$7 online and usually approves within minutes, but apply days ahead rather than at the gate. The airport operates 24 hours.
Leaving YYC during a layover
An eTA covers both transit and leaving the airport, so once documented, exiting is simple — but it has to exist before you fly. Downtown is about 17 kilometres northeast, and there is no rail link: the Green Line LRT extension to the airport has been proposed for years and remains unfunded. Route 300 BRT runs direct to downtown along Centre Street for around CAD$4, taking 45 to 55 minutes; Bus 100 connects to the Blue Line CTrain at Saddletowne. The city is about 45 minutes away one-way; as a rule of thumb you want 5+ hours before exiting is worth the queues, and you should be back through security 90 minutes before boarding.
Worth your hours in Calgary
- Downtown Calgary along Stephen Avenue is the practical target for a layover, with the Calgary Tower and the plus-15 skywalk network keeping you indoors in winter.
- The Calgary Stampede in early July transforms the city and the airport with it — if your connection lands in that window, expect everything to take longer.
- Banff is 90 minutes' drive west and Lake Louise two hours, which puts the Rockies firmly out of reach on a layover. That is a stopover trip, not a connection.
Staying airside instead
- Because both terminals connect airside, the whole estate is reachable during a connection — including the Air Canada Maple Leaf Lounge near Gate 50 in Concourse C, which international departures can still use. That is unusual and worth knowing.
- Concourse E has its own separate airside area behind US preclearance, so once you are through, you are committed. Do your shopping and eating before you clear.
- Free wifi throughout, a 24-hour interfaith prayer room on the Domestic Terminal mezzanine, seven children's play areas landside and airside, and landside luggage storage on the Arrivals level.
Sleeping, showers and lounges at YYC
Sleep: There is no airside transit hotel. Hotels sit around the airport landside and downtown is 45 minutes away, and with an eTA in hand reaching either is straightforward. The airport is open 24 hours, but it is a quiet and cold place to spend a night. Airport hotels & sleep pods
Showers: Shower access runs through the lounges rather than as a walk-up facility, so it depends on airline status or a lounge pass.
Lounges: Four lounges: Air Canada's Maple Leaf Lounge near Gate 50 in Concourse C, a WestJet lounge, and two Aspire lounges — one in Concourse D and one in Concourse E behind US preclearance. The Aspire in D is open to all passengers rather than premium cabins only. Because the terminals connect airside, lounge choice is more flexible here than at most North American airports.

Dietary needs: Canada beats the US here: alongside 10 priority allergens it separately mandates gluten-source labelling — barley, oats, rye, triticale and wheat — so packaged goods are genuinely reliable. Airside range is narrower than the eastern hubs, so buy early rather than at the gate.
Overnight reality: YYC is open around the clock and the YYC LINK runs airside, but there is no preclearance after 8pm, so a late US-bound connection means an overnight wait for the morning opening. Factor that in before booking an evening arrival with an early US departure — an airport hotel is usually the better answer than the concourse.
YYC layover FAQ
Do I need an eTA to transit through Calgary?
Yes, if you hold a visa-exempt passport such as Australian, New Zealand, British or most EU — Canada requires an eTA even for transit. US citizens are exempt. It costs CAD$7, is applied for online and usually approves within minutes, but apply days ahead. Note that even on an international-to-international connection where you stay airside, you still clear Canadian Immigration at dedicated transit counters.
What is the two-hour metering at Calgary?
Access to US security and CBP preclearance on Concourse E is metered at two hours before your scheduled departure — you cannot get through earlier even if you arrive with time to spare. Exceptions apply for travellers with mobility aids, families with small children and accessibility needs. Preclearance operates roughly 4:30am to 8:00pm, and US flights departing after 8pm do not get it.
How do I get between Calgary's terminals?
A 620-metre walkway connects the Domestic and International terminals, served by the free YYC LINK electric shuttle. Walking between the two farthest gates takes about ten minutes; the shuttle reduces it to roughly three. Both terminals connect airside, so a connection needs no second security screening.
Is there a train from Calgary Airport to downtown?
No. The Green Line LRT extension to the airport has been proposed for years but remains unfunded. Route 300 BRT runs direct to downtown along Centre Street for around CAD$4 in 45 to 55 minutes, and Bus 100 connects to the Blue Line CTrain at Saddletowne. Downtown is about 17 kilometres from the airport.
