Anyone else "read" the content of the QR code on the boarding pass graphic?
No, but that was pretty funny.
I used to scan my electronic boarding pass with a QR reader to determine in advance whether I was cleared for TSA Pre-check. There is one particular field that has a 3 in it.
But, most of the airlines are adding a Pre-Check icon to the electronic boarding pass. So, I no longer have to decode it myself. And after you mentioned it, I notice the sample boarding pass has the Pre-Check icon.
It's been a while since I flew Southwest, but my last time they didn't support Pre-Check. It's nice to see they have added it, and I can use it at my home airport.
If you fly more than a couple of times a year, I highly recommend enrolling in Pre-Check. It's worth it, especially if you depart from Las Vegas, Orlando, or Dulles during peak periods.
For a bit more money, you can enroll in Global Entry and also avoid the Customs and Immigration lines when returning to the US. However, the Customs and Border Patrol have fewer offices nationwide, and there might not be a convenient one near you.
