Carrier ML?

There is a couple listed for one of my flights I hope to take with "ML" as the airline. They show active with a seniority date of 1999.

I know ML to be Midway Airlines.
They folded in 1991 so "active" does not seem possible.
Is this something else other than Midway?

Thanks!

How about Olympic charter ML for Greek Islands?

I was told today that it is active employee on military leave.....

well, who knew?? Sure makes sense! Moreso than medium-large...
