Now that United's 747s are gone, Delta has announced their plans for saying goodbye to the Queen of the Skies. They will be doing a farewell tour starting in Detroit then going to Seattle, Atlanta, and ending in Minneapolis on Dec 20th with a hangar party at each stop. Unfortunately these flights and events are not open to the public or I would be there when it comes to MSP. They are auctioning off a few seats on the flights, but bids are in SkyMiles and not cash. After the farewell tour, they will be using the 747s for some charter flights through Dec 31st.

Such a shame to see them go. My dad used to take me airplane watching all the time when I was growing up and I remember watching these 744s wearing the "Bowling Shoe" when they were brand spanking new.
