Aviation United customers can bid on trip to 747 graveyard By Robert Silk / May 16, 2018 Share 1 -- United retired its final Boeing 747 in November. However, the carrier is giving aficionados of the original jumbo jet another chance for a United 747 experience. An auction currently live on the MileagePlus Exclusives website gives MileagePlus members the chance to use MileagePlus points to bid on a June 1-3 trip to Memphis that will be centered around a June 2 excursion to United's aircraft disassembly center in Tupelo, Miss. United has three 747s at the disassembly center.In Tupelo, the five winning bidders along with one guest each will be treated to a private tour of the disassembly center. The tour will end with a champagne toast in the first-class cabin of the aircraft that flew from San Francisco to Honolulu on Nov. 7 in what was United's last 747 revenue flight. After that, the auction winners will have dinner under the belly of the plane. United has made two of the auction packages available to all MileagePlus members. Two more are reserved for MileagePlus Premier members. One package is reserved for MileagePlus card members. On Wednesday morning, 156,000 award miles was the top bid.
