Alaska Air and Delta are ending their partnership

Alaska Air Group and Delta Air Lines are ending a codeshare agreement as competition between the two carriers serving Seattle-Tacoma International intensifies following Alaska Air’s takeover of Virgin America. As of May 1, Delta and Alaska will no longer have a codeshare agreement, and sales of flights under DL- and AS-coded flight numbers flown on Alaska and Delta aircraft will end. Delta and Alaska today codeshare on a small number of flights as Delta's flights out of Seattle-Tacoma International have grown and reduced the need for codeshare flying. The airlines also are ending their agreement allowing customers of each airline to earn and redeem Delta miles or Mileage Plan miles on flights operated by the other carrier. Delta said Monday that Delta and Alaska Air will retain an interline agreement. <br/>
