Code on boarding pass
 

Emptying a shirt's pocket before its trip to the cleaners this AM, I took note of my boarding pass from Tuesday. In the "OnePass" field, it had :
XX123456 Platinum / ST2

Never noticed that "ST2" before. Anyone know what it means? I had an upgrade standby companion with me, and it was the return leg of an RT, but beyond that, I have no hypotheses.

Sky Team ultra high muckiddy muck.

Congrats!!!!! ^

To be more clear: you're SkyTeam Elite Plus.

Thanks. And just to save others the trouble, I will lecture myself: "Use the search, bozo."

yes noticed that too, guess it was because I was banking my miles with DL. But what about the 2 digits that appear. On my passes today, one had "16" and one had "10" What's that?

It's probably the sequence number. It starts at one and increases by one for each passenger who checks in for a flight. 16 means you were the 16th person to check in for that flight.
