Delta Air Lines (NYSE: DAL) and Alaska Air have ended their partnership in a decision that will allow Alaska to focus on its merger integration with Virgin America and Delta to focus on creating more customer choice at its Seattle-Tacoma (Sea-Tac) International Airport hub, the companies said.
Effective May 1, 2017, Delta and Alaska will no longer have a codeshare agreement and flight numbers coded DL- and AS- (respectively) will cease. The carriers will retain an interline agreement, allowing them to continue offering customers ticketing and baggage connectivity.
Delta operates 150 peak-day departures to more than 40 destinations from Sea-Tac airport. Delta Air Lines serves nearly 180 million customers each year. Headquartered in Atlanta, Delta employs more than 80,000 employees worldwide and operates a mainline fleet of more than 800 aircraft.
