I am a lifetime PM on DL, and appreciate the Medallion upgrades, which can kick in 5 days before travel date. Do not always get them, but I have no complaints.
Just logged on and noticed that I have been upgraded already -- more than 5 days out -- for a trip in early March! I received a confirmation E-Mail for 1 of the segments, but upon accessing my PNR I noticed all segments had been upgraded..
Checking inventory (via the Internet, so I am cautious about it) shows all classes of booking still available, including the lowest, implying that there is no inventory reason for moving me up.
Not sure why I was upgraded early -- is this is a glitch crossing the end the short month, or a new policy? Not complaining, though!!
Just curious. Does anyone have an input?
