This will change soon (this summer) when Lawful Permanent Residents with Global Entry will be fully integrated into TSA Pre✓� if they include their Pass ID number into the field for Known Traveler Number when completing their details for the airline. There will remain the possibility of random exclusion for security reasons: just as US citizens are liable for random exclusion.

Another data point. Not a US citizen nor permanent resident, but have Global Entry. I use BA for FF not AA. I get TSA Pre pretty much every time when the BP is issued by AA (whether the is flight is operated by AA or whoever), domestic and international.

That's pretty much the case for me. I don't think I've consciously given AA my GE number, though I've now had one for about 3 years now, but from about a year ago I got more and more TSA Pre on the AA boarding pass. On US (and other airlines) they explicitly ask for the number in booking / check-in and that invariably works. However the value of it has somewhat declined, at LAX the difference is getting increasingly marginal.

Based on 10 or so recent transcon US flights, the increase in people using this line is great news as it simply reduces the waiting time at the others.

Not that dissimilar from people who insist on using a business / first queue with several people waiting in front vs. just switching to the empty economy one next door.

I pretty much always get TSA Pre when flying AA, and I attribute this to my BA Gold status.

If you fly AA intl F from JFK you get spat into the TSA Pre line, even if your BP doesn't say "Pre". On the 77W it's the only difference I can find between J & F in five flights (apart from the familiarity of the instantly recognizable Air Marshalls in F)

Ditto although I'm doubtful that it's down to being a GCH. I say that because a colleague of mine who is a GCH is Pre-Approved much less often since he lost his EXP status with AA.

For internal US flights Pre Check is a god send! That said, I'm on a domestic AA flight out of LAX right now and lone behold the Pre check at terminal 4 was closed. So, I had to pull all my liquids out, take my laptop out etc and there was general chaos from the folks who are used to Pre and leaving everything in their bags being made to drag out liquids and laptops etc.

Usually I'm in and out of security in minutes with Pre (except tonight). Glad to hear our UK bothers and sister can take advantage of this service!

I have consistently had TSA PRE on boarding passes issued by AA since I've had GE as I always put my known traveller ID into my AA bookings. I am flying on AA today TPA-DFW-LHR but on BA ticket stock but neither I (at home) nor the check-in agent (at TPA) could print my boarding passes with TSA stamped on them. She could see my known traveller ID in the AA reservation. Is it perhaps because the ticket is on BA stock?

After a couple of minutes we decided it couldn't be done today so off I trotted knowing I could use the priority line anyway. As it turned out, the priority line was closed and there was a massive queue of people.

I have been very spoiled over the last few years but had to suck it up this time and wait along with everyone else.

One more data point: I have GE; not a US citizen nor permanent resident; I used to have TSA Pre sometimes, and sometimes not, until I put my Known Traveller ID in my AA.com profile. From that point forward I have always been in the Precheck line.

There is now the ability of adding the Known Traveler ID in AA's equivalent of Manage My Booking without having a profile. I only noticed it fairly recently, about 6 months ago. I get Pre Check all the time now, I am Global Entry, but I'm not a US citizen nor do I have an AA.com profile. No Global Entry on BA flights however since BA is not a participating airline.

So on the USA AA.com - My Trips / Continue without logging in / enter locator / Passenger Summary / Add - Edit Passenger Information / Secure Flight Information / Known Traveler ID, which is typically an 8 digit number.

There's a more overt tab for this on US Airways' equivalent to MMB.

I was actually referring above to AA flights but on BA ticket stock. My personal evidence is that I get 100% TSA Precheck on AA flights booked on AA tickets using my known traveller ID (global entry) but 0% (Ok I only tried it today for the first time) on AA flights booked on BA ticket stock.

The agent could see that my known traveller ID was in the AA record but it wouldn't print or appear on my BP. The only difference I could think of is that it's on BA ticket stock. Do you think that might explain it or perhaps it was a one-off glitch?

Not a glitch, well it would have been a glitch if it was the other way around. It's not about ticketing airline, but operating airline. So BA is not an operator under TSA's scheme and therefore it should not get Pre Check. Ditto for AA tickets on other codeshared metal outwith Pre Check.

Ok thanks. If I read you right, I should have been able to use TSA pre today as the sector was operated by aa?

Yes from TSA's point of view, but no from a practical system point of view since the boarding pass was relating to air service BAxxxx rather AAxxx with therefore no known traveller information sitting in GDS/AA's systems. BA own the booking and the passenger information. Must have been annoying!
