Delta Air Lines
SkyTeam expanded in 2010 and 2011 with the announcements of additional airlines that will be joining SkyTeam in the future, including ones in China, Indonesia, and Argentina. It’s expected to grow to 19 members by 2012, with a stronger network in Southeast Asia, the Middle East, and Latin America. For example both Saudi Arabian Airlines and Middle East Airlines will be joining SkyTeam. The alliance also says it's continuing to consider potential partners in India and Latin America.
Future SkyTeam partners include:
Saudi Arabian Airlines
Middle East Airlines
SkyTeam members must meet the over 100 specific safety, quality, IT, and customer service standards (covering things from elite mileage recognition to lounge access) that are set by the organization. Audits of member airlines are performed to ensure requirements are being fulfilled.
Benefits of flying on SkyTeam airline alliance partners include the organization's Inter-Airline Through Check-in. The Inter-Airline Through Check-in lets an agent from any SkyTeam airline assign seats and issue boarding passes for a traveler's connections on other alliance airlines. Perhaps even more important for business travelers, if you're a SkyTeam Elite Plus member, you are actually guaranteed a seat (economy class) or reservation on any SkyTeam long-haul flight, even if that flight is sold out! In order to take advantage of that perk, you need to call the airline 24 hours in advance.
