Should be o.k. if bags are checked through and OSS is in effect for your flight (probably won't know until your flight is about to land), you go through the ITD transit clearance (assuming it's open). Either way, it should be barely sufficient, or even sufficient with a slight delay. The wild card is baggage delivery at YVR if you do have to retrieve bags. At any rate, domestic security should ne slow that time of night.

Someone asked about a similar connection (BA=>AC on separate tickets with a shorter connection), Was advised not to as the BA flight apparently doesn't have good on-time record.

Should be o.k. even if your flight is 1 hr late. The wild card is if domestic-to-transborder preclearance is open. If you have a GE card, there may be priority security clearance at either point.

The website currently says preclearance at YVR is now open to 23:30, but there's no mention of whether Christmas Eve operates under different hours (how can I check?). I do carry my GE card when traveling (ever since CATSA gave me grief over it in YYZ a few years back).

Would I be better served taking the shorter connection at YYZ even if it's on paper riskier? I have no idea how difficult a 1:15 I-D connection is at YYZ (AC International to AC Domestic). Some threads elsewhere on FT pre-pandemic indicate it should be doable within 30min. I assume traveling on Christmas Eve should be pretty slow as well, assuming things are similar to US travel patterns.

Edit: or does it not matter if USA preclearance is indeed not open and I end up having to go through uhh, is it the D gates?

MIL flying back from China via China-ICN-YVR-YWG. OZ->AC->AC. Reading the guide should be ok with no need to recollect luggage? Normally that's the case but does it matter the origin is China? We haven't done this routing in awhile. Usually just AC-AC from other places so no issues. Thanks!

There's preclearance for travellers coming in from landside (i.e., originating) and pre-clearance for transit pax (from domestic) and IIRC they were separate facilities (never experienced Intl => U.S.). You want the latter to be open. May not be too much of an issue going through the main preclearance facilities that time of the evening if you have to go landside as the dom => transborder other than for the walk .

Really a coin toss. Delay for inbound int'l flight, delays leaving YYZ, etc. X'mas is the major travel event here (not as much travel for Thanksgiving) Your advantage is that it'll be a Sunday and most except those who could not travel Friday/Saturday still have to get to where they're going to.

I think it's E for pre-cleared transborder (piers furthest east). D is int'l though one pier does have flex D/E gates.

It'll likely be open. If it isn't and you have to clear US entry at SEA, it'll be better as it's a faster connection D=>I (since no pre-clearance and maybe no add'l security). Just a long walk assuming it's on a DH-8 or some such.

Probably won't know until inflight.

is it the same procedure for non air canada? searched for westjet but nothing turned up. This would be Westjet to CI, so B to D I'm guessing

What's the itinerary?

YEG-YVR-TPE, one ticket, 5h layover. flight to TPE leaves 01:35

As long as WestJet doesn't encounter any problems checking you in and checking your bags though from YEG (which they shouldn't), yes, it's the same for your connection. Follow the signs from the A/B gates where your WS flight comes in to the international (D) gates. There's a small desk near gate 50 where they'll verify you're travelling internationally (just a BP scan; the automated gates usually work fine), then you're in the international area.

No need to re-clear security.

It's a bit of a hike, with only a few relatively short moving walkways, but with 5 hours, you shouldn't have any issues.

We're flying YVR-DFW Jan 2 at 7:00AM. What time do the US authorities open up pre-clearance? I recall a few years ago standing in a queue and waiting.

Can anyone confirm it opens at 4:30AM?

Looks like 1st U.S. flight out is at 0600 (AS/QX to SEA) so 0430 as the YVR site states is plausible, and stated by CBP as below

Is this the right thread to ask if there is a bus that connects Seattle with YVR airport? Or the other way round?

I can find buses from Vancouver to SEA airport, but what about YVR to Seattle? I found mentioning of Quick Shuttle, but they don't actually offer that.

Why not?

Don't remember if Quick Shuttle has stopped at YVR in recent years (might have done so 15-20 years ago). Currently, looks like you have to take the RAV line to Bridgeport and get the QS from the casino hotel. Other (and quicker if schedule fits) alternative is get the hotel shuttle to the Sandman Signature (the former Delta right by the highway and not the smaller one close by) and take the 4x daily Cantrail (Amtrak codeshare) bus. This one is non-stop to King Street station other than for the border stop.

There's Flix/Greyhound/Bolt or whatever but looks like you have to go all the way into town (main rail station/bus terminal).

PHX→YVR→KIX checked baggage question
 

Just got tickets PHX→YVR→KIX all on AC with an overnight 16hr layover in YVR. We're going to a hotel to sleep. My question is, do we need to get our checked bags and take them with us or will the bags be forwarded to the next flight?

Thanks for the thread and info.
