So, my husband and I fly frequently on United, and we are both members of PreCheck. We noticed that neither of us ever got the three beeps of approval to enter the PreCheck line, and went to ask United about why. After getting the run-around from the 1K service phone line, from check-in agents, from numerous customer service people who all claimed that the problem was TSA didn’t randomly select us for PreCheck (dozens of times in a row for people who belong to the program and get precheck consistently on every other airline? Sure….), we finally located someone who explained how to fix the problem on United’s reservation system!

And here, I pass that information to you. If you’ve been shut out of PreCheck on United, you’ve got quite a mission ahead of you. Fixing each reservation requires dogged persistence, because about 9 out of every 10 United employees has no idea what you are talking about and will shut you down with some vague blame-the-TSA nonsense. Don’t believe it for a second. The problem is United’s reservation system.

First, this has absolutely nothing to do with whether your PASSID number is properly associated with your frequent flyer account or whether your frequent flyer number appears on that flight reservation. All those items were in line for us, and still we didn’t get precheck. This problem is specific to and must be fixed at the level of each individual reservation record for each flight.

A quick glance at your reservation record will reveal whether the TSA precheck information got associated with this flight. There should be a line that reads

SSRDOCOUAHK1//K/123456789///US-1LASTNAME/FIRSTNAMEMIDDLEMRS

where the 123456789 is your PASSID number for TSA Pre-Check.

The letter “K” is for precheck (known traveler) and the letter “R” also sometimes appears there (which stands for a redress number, but relatively few travelers have those). We have been unable to understand why that line doesn’t appear in so many of our reservations. The problem might have to do with third-party bookings as we travel on business. Or this might have to do with some name-matching issues relating to the middle initial/middle name/ no middle name or the Mrs/Ms/no salutation distinction.

To fix this, the agent should enter the GG Secure Flight screens. The line that should be changed is the G*103 line. This is the line that should contain your PreCheck passid number, but often doesn’t.

I’m posting an image of the screen that shows formatting instructions to fix the precheck entry. Here are the instructions, which are listed on
UA DATA PAGE SECURE FLIGHT CATOC SUB: GEN PGE:SCF

ADD THE APPROPRIATE NUMBER USING THE FOLLOWING SSR FORMAT:

3SSRDOCOUAHK1//K/123456789///US-1LASTNAME/FIRSTNAMEMIDDLESALUT
The 123456789 should be your PASSID number, and the FIRSTNAMEMIDDLESALUT needs to match the exact format of the name including MR or MRS for that particular reservation, or the system will reject the change. Accepted changes print an asterisk in response.

If there is an incorrect entry in the record, then that must be removed before the correct entry can be added. The way to remove an incorrect entry is to type 314□ hit enter, then type ER. Note that the open square box is actually a box with an x through it, but that special character doesn’t appear in my fonts.

You can always decode the barcode on your boarding pass before you fly and see whether the magic “precheck 3” is included in your boarding pass. However, we’ve never had success with updating a United reservation after a boarding pass was issued – that might be too late to get into the precheck bucket.
