Char 69: Day of year of check-in...correct, Julian date one less then above since I checked in the night before
Char 73: Marketing airline code (correct, says BUA)
Char 89: Not sure, AA puts 29 here, AS puts 25. (my BP says 0E here)
Char 91: Ticketing airline 3-digit code (001, 027) (correct, 016)
Char 94: Ticket number (mine has no ticket number included)

After this, there is one more stray "3" a few spaces later.

After that, I get what looks like a bunch of either binary or encrypted text. This was when scanning the Aztec mobile boarding pass on my phone with another phone. When scanning the PDF417 version on the emailed BP, I don't get anything after the couple of spaces followed by a 3.

Unfortunately, I won't be able to check if it was Pre eligible because I am going out of SNA and there is no Pre. I've noticed that their scanners don't seem to indicate Pre at all. Instead of being the kinda standalone scanners mounted on a pole (big black metal box), they instead have the kind that are integrated into their little podium. I haven't heard any beeps out of them. I can try to look and see if LLL shows up at all.

Note that I have gotten the triple beep at DEN (also not Pre) and on DL at SLC (actually got to use Pre), so I know it is working for me
