Letter on the back of BPs
I was really bored, so I decided to go through my old boarding passes. I noticed something odd on the back of the majority of my BPs. In the upper left corner of the magnetic strip there is a tiny letter. In about 70 BPs, I have the letters A through E, while a few BPs have no letter printed. Does anyone know the purpose of these letters?

Oh, you have a ways to go. Once you collect BPs with one of each letter, A-Z, you can turn them in for instant UGS status for life.
OK, I'm kidding.

I think they're codes relating to the print runs or something to do with the printing.
Interestingly I just looked at the back of a few QF passes I have handy. One of them has: A B C D E F G H I J K L M N O P Q R S T U V W.
Another one starts a E...
Actually now I come to think of it it reminds me of a previous life when I worked in the production/printing area of a major daily newspaper. Anyway they used to print various letter codes (eg: A , B etc) each time they changed the plates .. or rather, as a version control. So the first set of papers printed would be an A, then if they changed something, edited something, added a late sports score, updated an article(whatever), the next run might have a B on it and so on. That way you could tell which version you had (I think some papers use series of stars, and/or print stuff like "FINAL"). It was basically a version control system.
The other reason to do it may simply to be as a test of the letter rendering of the print process. I dunno. I'm not a printer. I'm sure it's got something to do with it though
(a new way to learn the alphabet when bored on long flights? )

I'm just amazed that someone actually SAVED boarding passes from the 70's and still had them (let alone saved enough to perform some analysis on letter codes on the back 
)
)

uhh i'm pretty sure the OP said he had ABOUT 70 bp's, not FROM the 70's
Problem is with many of them having been printed thermally...they're fading away to nothing!
Gonna have to hire some kid to go through and make photocopies before they are all gone. Although I don't know why I should even bother anymore. Seemed like a good idea at the time to save them.
