Thanks.

I've updated the wiki.

The only thing airline is submitting for PreCheck on top of what that normally submit to serve US market is KTN#. Airline do not submit travel patterns as part of PreCheck.

I don't see how privacy regulation would prevent airline from submitting KTN but allow for submission of passenger name, DOB, travel document etc.

Do you have access to the documentation for the precheck data submission system? I'd love to see it.

Are you 100% sure the airlines agreements with the TSA do not contain any data-sharing arrangements?

Would be interested to see if when SQ rival CX start to look into this.

I think the question is really what is there left to share that has not already been provided via SecureFlight, APIS, ESTA for VWP or visa application for non VWP? According to border security reality TV show, CBP apparently can also pull ticket purchase information as well. All this information is already provided to US for general passengers.

What information is there left to share for PreCheck?

televisor

Things like travel history for flights that don't touch the US. ESTA doesn't ask for a list of all visited countries, never mind all visited cities.

From what I'm aware frequent flyers used to commonly get Pre without a KTN, that could be based on status being transmitted (is that transmitted as part of SecureFlight?), or it could be based on actual travel history submitted by the airline. Given the lack of public information on this, who knows?

seawolf

Only evidence of data for PreCheck is submission of KTN. As part of obtaining KTN, you should have already truthfully provided that travel history you are concern about.

Foreign nationals can't even obtain KTN without submitting to background check conducted by foreign government. That information would be obtained by US government from the foreign government than a foreign airline.

I was wonder if BA or KLM will join TSA PreCheck anytime soon? I know other airlines who did not join TSA PreCheck.

Flying BOS-IAD-NRT and NRT-ORD-BOS, where the US domestic flights are UA and transpac flights are NH. NH single award ticket.
-For the outbound, do I need to call UA to add KTN for Pre to populate on BP?
-For the return, to get Pre in ORD after Immigration/Customs, does one need to have a new BP issued by UA?
Thanks much!

Yes call or go online with UA to add KTN/ensure name is correctly entered in secure flight data name fields.

Yes UA would need to issue you a BP to get Pre. May be able to pull it up in the UA app after the NH flight lands.

Perfect thanks!

It's possible that they're working on it. Collecting the KTN and forwarding it as part of the ticketing info is a lot easier than sending it and encoding a response from the TSA. Part of the Precheck requirements is that the boarding pass is digitally signed (if you alter any of the plaintext elements of the barcode, like name or departure/arrival city, then the TSA scanners will recognize it as invalid. It's not known (as far as I've read) whether the TSA signs the responses and sends it back to the airline for inclusion in the barcode, or if TSA merely sends the response (precheck/normal/SSSS) and then the airline uses their own private key to sign the boarding pass.

Another option is that HU might be forwarding the information on as part of tickets issued by other airlines.

The issue is that the trust is currently tied to the boarding pass and an offline read at the boarding pass station. The airline has to integrate with TSA to get a response on whether or not precheck is offered, and sign all boarding passes with a digital signature (if they're altered, whether it's the name, or destination, or the fact that someone got prechecked, the scanner can detect it because the signature won't match). You have to change your boarding pass generation to get this response, process it, and react accordingly.

They are testing credential authentication technology at US airports, which instead scans the person's identification document (license, passport, etc.) and then references it against secure flight. At that point, a boarding pass indicator/barcode inclusion would become a moot point, since they could just look it up from secure flight. Of course, the ticketing airline would still need to submit the information to Secure Flight as part of ticketing.

Signature is only required on digital BP. Paper BP are not signed. Therefore, it is unlikely TSA response is signed.

I was wonder if Condor will ever join TSA PreCheck anytime soon? I schedule for next flight from PHX-FRA-BSL on May 18, 2018. Should I call Condor to put on KTN?

According to the Condor web site, they don't collect the KTN (they do collect a redress number if applicable).
