Yesterday a friend of mine who works for Delta sent me a message with the following:

Delta is reducing MEM service by 15%. MEM will be down to 94 departures.

Fort Lauderdale, FL (FLL), Jacksonville, FL (JAX), and Birmingham, AL are being eliminated from MEM.

The following cities will see frequency reductions:
Little Rock, AR (LIT)
Saint Louis, MO (STL)
Nashville, TN (BNA)
Raleigh-Durham, NC (RDU)
Knoxville, TN (TYS)
Jackson, MS (JAN)
Kansas City, MO (MCI)
San Antonio, TX (SAT)
Tulsa, OK (TUL)
Los Angeles, CA (LAX)

I'm not sure of the exact dates but was told these cuts would take effect early in 2013.

MEM is now under 100 daily departures. I'm not sure how much longer it will be able to hang on.
