I have been flown on DL but, it was not too much people the flight from PHX-SLC. It was very emptied flight in Y class but, I am gotten upgradeable in F class from PHX-SLC. It was almost full of F class instead of Y class. When DL agents was called me while I was at the gates. She gave me F class but, I got score upgrades into F class. It is great opportunities from DL agents is gave me into F class for PHX-SLC but, not for SLC-FLL is full. When I got get back to PHX. I got upgradeable into F class all the way to PHX. That's why I am being lucky for flying into F class instead of Y class. Because my medallion is expired last week. If I could flyable more with DL this month & next couple months will try more mileage runs. I will try toward FO again for 2009.
