Everyone who travels with Delta Air Lines knows about SkyMiles and its rewards program. Depending upon how frequently you travel with the airline, you have plenty of options, such as the Gold Medallion Status or Platinum or its most luxurious Medallion Status – Diamond. But despite the name Diamond having a zing of certain elite status, it isnt the highest tier that a traveler with the airline can apply for. Delta Air Lines most elite status cannot be applied to – it is the airline that dictates whom it will give the gift of the 360 status.
