Airline Alliances: The Global Networks Connecting the World

An airline alliance is an arrangement between two or more airlines to cooperate on a substantial level. While alliances often provide marketing and branding benefits-such as facilitating inter-airline codeshare connections or creating a more unified customer experience-their impact goes far deeper. Alliances expand global reach, streamline passenger flow, and enable joint ventures that would be difficult, if not nearly impossible, for a single airline to manage alone.

The Big Three Alliances (and the Most Established Alliances) of the World

1. Star Alliance

Founded in 1997 by five airlines-Scandinavian Airlines (SAS), Lufthansa, United Airlines, Air Canada, and Thai Airways International-Star Alliance is the largest and oldest major airline alliance in the world.

(Note: SAS later left Star Alliance and joined SkyTeam following its restructuring involving Air France-KLM.)

Today, Star Alliance has more than 25 full member airlines, along with numerous codeshare and partnership relationships.

Notable full members include:

Europe:

• Aegean Airlines
• Austrian Airlines
• Brussels Airlines
• ITA Airways (successor to Alitalia and the flag carrier of Italy)
• LOT Polish Airlines
• Lufthansa
• SWISS
• TAP Air Portugal
• Turkish Airlines

Asia-Pacific:

• Air China
• Air India
• Air New Zealand
• ANA
• Asiana Airlines
• EVA Air
• Singapore Airlines
• Thai Airways

Americas and Africa:

• Air Canada
• Avianca
• Copa Airlines
• EgyptAir
• Ethiopian Airlines
• South African Airways
• United Airlines

Future considerations:

• Emirates has explored potential alliance opportunities, including possible cooperation with Star Alliance.
• JetBlue Airways has expanded cooperation with United Airlines through the Blue Sky partnership, though future alliance membership remains subject to confirmation.

Unique partnerships

Star Alliance has developed partnerships beyond airlines. For example, Deutsche Bahn (DB) allows travelers in Europe to integrate rail connections with airline journeys, expanding the alliance's transportation network.

Not only is Star Alliance the world's largest airline alliance, but it is also particularly focused on helping travelers connect globally while supporting the growth of its individual member airlines. United Airlines, for example, has increasingly focused on helping travelers navigate global journeys more efficiently and with less stress-something we value here at Brooke In The Air Travel! (Couldn't resist a plug. Now, back to the article.)

Fun fact: Star Alliance is the only major airline alliance not headquartered in the United States. Its headquarters are located in Frankfurt, Germany, near Lufthansa's primary operations at Frankfurt Airport.

2. Oneworld Alliance

Founded in 1999, Oneworld has 15 full member airlines and is the second-largest major airline alliance.

Members include:

Americas:

• Alaska Airlines
• American Airlines (founding member)
• Fiji Airways

Europe and Middle East:

• British Airways
• Finnair
• Iberia
• Royal Air Maroc
• Royal Jordanian

Asia-Pacific:

• Cathay Pacific
• Japan Airlines
• Malaysia Airlines
• Qantas
• Oman Air
• SriLankan Airlines

Future considerations:

• STARLUX Airlines of Taiwan has expressed interest in joining Oneworld, with discussions continuing regarding potential future membership.

Oneworld focuses heavily on premium service, frequent flyer benefits, and long-haul connectivity, particularly across Europe, Asia, and Australia.

3. SkyTeam

Founded in 2000, SkyTeam is the youngest of the three major alliances and is currently strongly associated with Delta Air Lines.

Notable members include:

Americas:

• Aerolíneas Argentinas (flag carrier of Argentina)
• Aeroméxico (flag carrier of Mexico)
• Delta Air Lines

Europe and Middle East:

• Air France
• KLM
• Middle East Airlines (MEA, based in Beirut, Lebanon)
• Saudia (flag carrier of Saudi Arabia)
• TAROM
• SAS (joined SkyTeam in 2024 after leaving Star Alliance)

Asia-Pacific:

• China Airlines
• China Eastern Airlines
• Garuda Indonesia
• Korean Air
• Vietnam Airlines (often associated with the "Flying Lotus" nickname due to its branding)
• XiamenAir

Other members:

• Virgin Atlantic (United Kingdom)

SkyTeam focuses on improving global connectivity and strengthening transatlantic and transpacific partnerships. Some airlines, such as Aeroflot, have been suspended due to geopolitical sanctions related to Russia's invasion of Ukraine.

Why Alliances Matter (and Why Travelers Should Care)

Global reach

Passengers can travel farther on a single itinerary across multiple carriers.

Seamless connections

Alliances help coordinate flight schedules, baggage handling, lounge access, and passenger services.

Joint ventures

Airlines collaborate to optimize routes, especially long-haul services, while sharing operational risk and revenue.

Codeshare partnerships

Passengers can purchase tickets through one airline while traveling on another airline's aircraft, creating more options and flexibility.

Star Alliance, for example, excels at creating interconnected routes, particularly across Europe and transatlantic markets, by leveraging its extensive membership network and partnerships.

Why Only Three Alliances Matter Globally

You may notice that I only covered three alliances. There is a reason they are considered the "Big Three."

Other airline partnerships and alliance models exist, but many are smaller, less stable, or frequently changing. Airlines may join and leave these arrangements within short periods, or partnerships may dissolve due to mergers, acquisitions, or changing business strategies.

Airlines such as Emirates and Etihad Airways, both popularly viewed as luxury carriers, have historically chosen to remain outside the major alliances.

Their decisions were based on business strategy. Both airlines determined that operating independently allowed them to maintain greater control over their networks, branding, and customer experience while still achieving extensive global connectivity.

Emirates exploring potential alliance opportunities demonstrates that even independent carriers continually evaluate whether joining a larger network creates more value than remaining independent.
