NAV CANADA is metering arrivals into Vancouver International Airport tonight for reduced system capacity, not thunderstorms. Advisory 027 lists a 22-minute average hold and an 83-minute maximum through 12:59 a.m. ET.
The program covers departures from Canada and the contiguous United States. It is not the Las Vegas or Denver storm programs already live on Deep Arrival.
- Airport: Vancouver International, identifier YVR.
- Cause: Reduced system capacity, not weather.
- Hold: 22-minute average, 83-minute maximum.
- Window: Through 12:59 a.m. ET August 13.
- Scope: All Canadian and contiguous U.S. departures.
What the advisory actually says
The control element is CYVR. The arrival window is 12/2300Z to 13/0459Z, which is 7:00 p.m. ET August 12 through 12:59 a.m. ET August 13.
Delay assignment is UDP. The program rate steps through 25, 24, 24, 25, 27, then 23 arrivals. Those are flow numbers, not a promise that your flight will move in 23 minutes.
The impact line is OTHER / OTHER. The comment is REDUCED SYSTEM CAPACITY. That is a staffing or flow limit, not a thunderstorm cell sitting over Sea Island.
Departure scope is all Canadian and contiguous U.S. flights, with a second-tier list that includes western U.S. centers such as Los Angeles, Salt Lake City, Denver, Oakland, and Seattle, plus Canadian centers.
If you are leaving Hawaii, Alaska, Mexico, or Europe for Vancouver, this advisory does not name you. Recheck the airline anyway. A late inbound from Seattle can still miss a bank.
UDP means the delay is assigned by a computer to keep the arrival rate at those stepped numbers. It is not a first-come line at the gate. Two flights that push back together can receive very different expected departure times.
Keep the advisory number. If an agent says only that Vancouver is delayed, ask whether the message is ADVZY 027 for CYVR. A generic delay remark can be a mechanical issue on your aircraft, not this program.
Who should act before midnight
If you are sitting at a U.S. or Canadian gate bound for YVR, do not leave the origin airport until the app shows a current departure time. An expected departure clearance can move after you have already given up the seat.
If you are connecting in Vancouver to Asia, Victoria, or Calgary, treat the 83-minute maximum as the risk, not the 22-minute average. A 90-minute Vancouver connection is not enough if the inbound is assigned the long hold.
If you are meeting a passenger at YVR, use YVR’s arriving flights board and add buffer after 12:59 a.m. ET only if the airline still shows the flight inbound.
Air Canada is the largest user of the Vancouver hub. Passengers on that carrier can start with Deep Arrival’s Air Canada route and cabin guide for the airline’s normal connection pattern, then follow tonight’s app time instead of the published bank.
WestJet, Porter, United, Alaska, Delta, and American also feed YVR from the listed scope. The advisory does not exempt a U.S. carrier just because the destination is in Canada. If the ticket says Vancouver and the origin is in the contiguous United States, assume you are in the program until the airline says otherwise.
People already in Vancouver who are only flying out tonight are not the target of an arrival GDP. Their risk is a late inbound aircraft that becomes their outbound. Ask whether the tail is coming from a U.S. or Canadian city inside the window.
How this is not Denver, Las Vegas, or Chicago
Denver’s August 12 program was a thunderstorm ground delay. Las Vegas was also thunderstorms. Those posts do not tell you anything about Vancouver capacity.
Chicago O’Hare later flipped from a storm stop to a staffing delay. That is still a different airport and a different control element. Do not apply O’Hare times to a YVR ticket.
Toronto Pearson and Montreal Trudeau had their own weather programs earlier today. A Toronto hold does not meter a Seattle-to-Vancouver departure.
The useful test is the three-letter code. If the airline message does not say YVR or CYVR, this advisory is not your hold.
What to do at the origin airport
Open the airline app and write the current departure time, the expected arrival in Vancouver, and any new connection. Screenshot it. Agents quote verbal times that later change.
Do not check a bag and then leave security for dinner unless the airline has reissued a later boarding pass. A UDP program can pull the flight forward as well as back.
If the inbound to your origin is already late, ask whether the YVR program is stacking on top of that delay. Two holds can exceed the 83-minute line even if the advisory average is 22.
International passengers who need to reclear in Vancouver should not assume a late arrival still makes a same-night Asia departure. Ask the airline to protect the onward seat before you board the first flight.
A worked check looks like this. Confirm the destination code is YVR. Read the current departure time in the app. Add 83 minutes to the scheduled Vancouver arrival. If that time breaks a connection, ask for a protected later onward flight before you leave the origin gate.
What remains unknown
The advisory does not name a staffing number, a runway closure, or a system outage. Reduced capacity is the public label. Do not invent a more precise cause.
The program can be revised or cancelled before 12:59 a.m. ET. A later advisory with a new average replaces this one. Refresh the FAA page, not a screenshot from 7:00 p.m.
YVR’s own operational snapshot may show a different passenger-facing delay than the 22-minute en-route average. The airport board is what greeters should use. The advisory is what departing aircraft are assigned.
If your flight is already airborne, the hold is behind you. Watch the arrival time and the baggage belt, not the origin ground-delay clock.
Hotel and ride bookings at YVR should be moved only after the airline shows a new arrival. A 22-minute average is not a reason to cancel a room. An 83-minute maximum plus a missed Asia connection is.
Do not drive to the airport to “see if it leaves.” The useful work is at the origin gate or on the phone with the airline. YVR cannot release a flight that has not been assigned a slot.
| If you | What to do |
|---|---|
| Are at a U.S. or Canadian gate bound for YVR | Stay airside and board only on the current app time. |
| Have a Vancouver connection under 90 minutes | Ask the airline to protect a later onward flight now. |
| Are meeting a flight at YVR | Use the airport arrivals board, not the 22-minute average. |
| Hold a Denver or Las Vegas ticket tonight | Ignore this advisory. Those are different airport programs. |
| Are already airborne to Vancouver | Watch the arrival time. The origin hold no longer applies. |
- Cutoff: The posted window ends at 12:59 a.m. ET unless revised.
- Revisions: A new advisory can change the 22- and 83-minute numbers.
- Connections: Same-night Asia and domestic banks can still break.
- Cause: The public label remains reduced capacity, not weather.
If you are bound for Vancouver from Canada or the contiguous United States tonight, recheck the airline app and do not leave the origin gate on the old departure time.
Is this a thunderstorm delay?
No. Advisory 027 lists reduced system capacity. Denver and Las Vegas were the storm programs tonight.
Does a 22-minute average mean I will be 22 minutes late?
No. That is the program average. The same advisory lists an 83-minute maximum.
Does this apply to flights from Hawaii or Europe?
The listed scope is Canada and the contiguous United States. Recheck the airline if you are coming from anywhere else.
When does the program end?
The current arrival window ends at 12:59 a.m. ET August 13 unless NAV CANADA issues a revision.
