Yup. Better phrasing: OSS can involve any combination EXCEPT Anywhere-USA. Dom-Dom, Dom-Int, Int-Dom, Int-Int, US-Int, US-Dom at YYZ can all be OSS.

Is this something I can pick and choose?
I actually want to pick up my bag when I land in Canada...
ill be Orlando-YYZ-YVR
I put extra few hours between YYZ and YVR so I can step out and see my family in Toronto.
I'll have gift for my dad in checked bag...

You're going to have to ask AC in Orlando to short check your bags to Orlando. An unlikely scenario is that you can ask CBSA to pull your bags. Of course unless they want to search your bags, I doubt they will do it...

From IAD-YYZ-YOW, I have "ITD OSS". Anyone seen this before?

Looks like it stands for International to Domestic. The only remotely relevant result I see on Google is for this thread, and for a job posting from March of this year that was reposted by a blog focused on aviation operation jobs.

Does anyone know if OSS applies if the trip originates outside Europe? Or if it applies to airlines other than AC? Flying SIN-ZRH-YUL-YTZ next week on LX and AC

A side note - any experiences checking bags through to YTZ from far, far away?

None of that applies as you'll have to pick up your luggage at YUL as LX isn't an ITD flight. Recheck your bags to YTZ after exiting CBSA.

OSS at YVR?
 

does anyone know if OSS is operational US to Domestic at YVR? I have ITD OSS only YVR to YUL BP.
thanksp

No it is not.

Bummer.
Thanks for the response

Do we have a full list of Canadian airports where OSS is operational? My cursory/lazy search implies just YYZ and YUL...

Good to know!

Glad I googled this thread. Mrs GHT, GHT Jr and I all got ITD OSS and I thought it was some secondary thing.....

i've a quick question.
flying muc - yyz - sfo tomorrow and OSS is on the Boarding pass YYZ SFO
1. Does i have any benifits with OSS , if so which direction i have to go after deboarding.
2. Why did i get OSS it's because of C or TSA/GE Member

1) No, there no benefit on that route as you must still clear US-bound security. Just follow the signed for US connections.
2) You get OSS because you're departing from an OSS qualified airport (MUC) on an OSS qualified carrier (AC), it is not dependant on C/J or GE, and is offered to first-time flyers in Y as well. Were you connecting to a flight within Canada or to a non-US country, it would mean that you wouldn't reclear security in YYZ. However, as the US demands a special level of security, you have to reclear anyways.

I think the logic behind the explanation is the USA currently only recognizes passengers who went through security screening in either the USA or Canada as "clean". So if you're flying from Munich to Chicago, you have to be re-screened either in Chicago (if flying nonstop MUC-ORD) or a Canada transfer airport to be able to board another flight out of Chicago.

Officially they accept the screening from any location that meet their standards, and every airport offering direct flights to the US is obligated to screen US-bound passengers to their standards. That's why you see separate US-bound gates / terminals with their own security at airport around the world, even those without preclearance facilities (think Z gates in FRA and E gates in ZRH). However, those airport don't necessarily screen non-US bound passengers to the same standards, and therefore the US won't accept in-bound OSS as it's not done to the correct standard.

The issue on MUC-ORD-SFO (for example) is that there is no sterile immigration/customs facilities in ORD (or any other US airport), so you'd have access to your bags and therefore would need to reclear security before your connection. However, if you arrive from a preclearance facility (and therefore don't need to use the immigration facilities), you're good to go assuming you land at the right terminal or can do a sterile terminal transfer. So for example AUH-JFK on EY can sterile connect to JFK-SFO on DL. Same would go for flights from DUB, SNN, etc..

If/when the US establishes sterile clearance/transfer facilities, you'll see this issue come back to the surface. Right now from a practical standpoint they only accept screening done at a preclearance facility. They don't have to worry about if they should accept screening done in, for instance, CAI, because there isn't preclearance there, so everyone needs to be recleared anyways.

Yes, you had the right explanation and I did not. Basically, it comes down to preclearance airports and the vast majority of those passengers are inbound from Canada. I guess we can add Dublin, Shannon, Abu Dhabi, and two or three or so in the Caribbean to that list. The key is they all arrive as if they are domestic flights.

Does YVR have any plans of implementing OSS?

I got this today for EWR-YUL-BRU (ITI OSS). WIll be interesting to see (all AC itinerary) what happens at YUL.

I'm no expert, but I'm under the impression that the current layout of YVR would need heavy modification to become OSS-compliant.

How did it go?

YVR
 

I thought about this again and think the litmus test might be an airport such as YEG. Those familiar with YEG know there's a special door that leads from the domestic concourse to US-CBP. I've never made a connection to the US at YEG so I've never gone through this door. If there's anyone out there who has made this connection at YEG, do you have to go through security screening all over again?

What makes YEG different than a place like YYZ is there's no commingling of passengers from overseas involved. The only people who can go through that special door are people who have been through security screening at a Canadian airport. For example, someone coming in from AMS to YEG would not be on that domestic concourse. This is different than YYZ T1 where inbound passengers making a Canada -- USA connection mix with other international to US passengers who just stepped off their plane.

ITD OSS has just started - 14JUL2018 in YVR. There is a bus from customs hall to domestic gates...takes less than 5mins.

Oooh nice. I am flying SEA - YVR -YUL tomorrow and I have the OSS text on my boarding pass. I always hated to go through security again. Is the bus clearly marked? Just to double check, I don't need to get my bags, right?

AC-AC. Yeah, lately we haven't needed to reclaim bags, but needed to go though security again... which is additionally annoying as they don't have a Nexus or priority lane. So the line can be long

FYI, currently in YVR, and I did have to go through security again. I asked a few agents and showed them my boarding pass, but no one knew about it. One person vaguely heard something about it, but said it ends at 10pm. (It was 10:30 ish)

I just did OSS off SYD connecting to YYZ (in YVR)

It saved at least 30 minutes from the old way. Just ... FANTASTIC

Following up on an old topic. It appears the US does not truly require screening at a pre-clearance facility for full access to connection in the US though, for practical purposes, it generally works out that way.

Case in point... I flew from YEG to DEN last week. Those familiar with YEG might have noticed there is a CAN --> US connection door on the domestic concourse at YEG. From what I could tell at the transborder security screening station, that door allows domestic connecting passengers to bypass screening and head straight to US-CBP. In other words, a passenger who has been screened in Regina or Fort McMurray is not re-screened at YEG when connecting to the US.

This is not the case at YYZ (I'm only familiar with T1 so holding my comments to that only) because there isn't a dedicated CAN --> US connection corridor at T1. Yes, there is a connection that bypasses Canada immigration but it only puts you with international arrivals. I believe this is why re-screening is necessary at YYZ T1.

In case anyone comes looking at this thread... I just flew SFO-YYZ-DUB, and my YYZ-DUB boarding pass had "ITI OSS" (International-to-International One Stop Security) above the scan block. After deplaning and walking towards connections, there was a lane to the left that was for international transfers. I showed my boarding pass, entered an area where I scanned my passport, got a receipt, then showed my boarding pass again to exit, down an escalator, and I was at the E gates. No customs, and no physical security re-screening. There was no one else using this route in front of or behind me, and total time was less than 2 minutes.

Weird failure condition yesterday.

DFW-YYZ-YHZ. 2 hour connection. I had some meetings that became important, so SDC to a later flight over the phone with the concierge[1]. On getting my BP reprinted the MLL agent asked the question about bags, answered it himself. Except, I did. The DFW contract agent did not actually check the bag all the way through.

So I had to leave airside, talk to a baggage agent, get escorted into the INTL claims room, move the bag across the border, and then re-clear security. Having done it before, and having the time, no biggie to me. But annoying AF.

Had I kept my initial connection, or not gotten a paper BP, my bag would still be in the INTL claims room.

[1] Unrelated gripe: SDC off a flight with several dozen on the standby list to a flight that took off with empty seats should not cost anyone $75.

Resurrecting old thread, but does OSS mean I can carry liquids through in my hand luggage (thinking duty free purchases in Europe when connecting with OSS BCN-YUL-BOS).

Just in case anyone else stumbles on this post. Yes OSS (through YUL at least) is much quicker than exiting and entering again, but you still get scanned and still lose your over 100mm liquids.

The only reason you had to go through security again was because you were connecting to the US. Americans want people to be searched right before customs up to US TSA standards so they don't try to harm one of their officers and can arrive as a domestic passenger in the US.

Yes, but then it's not really one stop security...
