How to Use

1
Choose an airline alliance to analyze
Select Star Alliance, SkyTeam, or oneworld from the dropdown. The tool loads the current member airline roster with their IATA two-letter designator codes and hub airports.
2
Enter an origin and destination city pair
Input the departure and arrival airports by IATA code or city name. The checker identifies which alliance member airlines operate or market service on that route.
3
Review alliance coverage and connection options
Examine which alliance members serve the route nonstop or via hub connections, and note whether the itinerary qualifies for through-check baggage and reciprocal frequent flyer earning under alliance standards.

About

The Alliance Route Checker identifies which Star Alliance, SkyTeam, or oneworld member airlines operate service on a given city pair, enabling travelers to plan itineraries that maximize alliance benefits including through-check baggage, lounge access, and reciprocal frequent flyer earning. Alliance membership lists are maintained against current IATA carrier enrollment records, reflecting additions and withdrawals as they occur.

The three global alliances were established in the late 1990s and early 2000s to enable seamless interlining on a worldwide basis. Star Alliance (26 members) focuses on comprehensive global coverage; SkyTeam (19 members) has particular strength in Asia-Pacific and trans-Siberian markets; oneworld (13 members) has strong transatlantic and Pacific presence. IATA's alliance governance framework requires members to maintain IATA Operational Safety Audit (IOSA) registration and to implement specified customer service standards for baggage, lounge, and frequent flyer reciprocity.

Alliance route analysis is valuable for corporate travel managers designing preferred carrier programs, frequent travelers optimizing award earning on multi-leg itineraries, and researchers studying competitive dynamics in hub-and-spoke network markets. Understanding which alliance serves a specific city pair determines whether an itinerary qualifies for alliance-level benefits versus purely bilateral codeshare arrangements.

FAQ

What are the three major global airline alliances?

Star Alliance, founded in 1997 with United Airlines, Lufthansa, Air Canada, SAS, and Thai Airways as founding members, is the largest with 26 member airlines and access to over 1,300 airports. SkyTeam, launched in 2000 by Air France, Delta Air Lines, Aeromexico, and Korean Air, comprises 19 members. oneworld, established in 1999 by American Airlines, British Airways, Cathay Pacific, Finnair, and Qantas, has 13 full members. Each alliance maintains an IATA-recognized governance framework that sets standards for interoperability, lounge access reciprocity, and frequent flyer tier recognition across member carriers.

How does alliance membership affect frequent flyer earning?

Alliance agreements require member airlines to recognize elite status from other member carriers, enabling reciprocal lounge access, priority check-in, and bonus mile accrual. Specific earning rates for partner airline flights are governed by bilateral agreements within the alliance framework rather than a universal alliance standard, so earn rates vary by carrier pair. IATA Resolution 724 and the relevant airline frequent flyer program terms define how partner miles are credited. Star Alliance Gold, SkyTeam Elite Plus, and oneworld Sapphire represent the mid-tier status levels that unlock most reciprocal benefits across member airlines.

Can a traveler earn and redeem miles across all alliance members?

Mileage earning on partner flights is standard across all three alliances, but redemption policies vary considerably. Most programs allow award bookings on alliance partners, though partner award space availability is typically more restricted than on the home carrier. Some carriers impose fuel surcharges on partner awards that can approach the cost of a revenue ticket. IATA's Multilateral Interline Traffic Agreements (MITA) govern the financial settlement between carriers when passengers travel on interline itineraries, and alliance award redemptions are processed through this clearing system.

What is the difference between an alliance member and a codeshare partner?

Alliance membership requires meeting specified standards across safety audits (IATA IOSA certification), operational interoperability, and commercial agreements. Codeshare partnerships are bilateral commercial arrangements that allow a marketing carrier to sell seats on an operating carrier's flights under the marketing carrier's own flight number, governed by IATA Resolution 788. An airline can have hundreds of codeshare partners without any being alliance members. Alliance membership implies a deeper and more standardized relationship including customer service standards, lounge reciprocity, and through-check baggage on same-day connections.

Are there alliance-specific routes that non-member airlines cannot serve?

Alliance membership itself does not grant exclusive route rights; commercial route rights are governed by bilateral air services agreements (ASAs) between sovereign nations under the Chicago Convention framework. However, alliance hubs such as Frankfurt (Lufthansa/Star Alliance), Paris CDG (Air France/SkyTeam), and London Heathrow (British Airways/oneworld) are strongly associated with their respective alliances, and hub capacity constraints effectively limit competition on certain spoke-to-hub routes. Open skies agreements, such as the EU-US Open Aviation Area, have progressively liberalized traffic rights within those blocs, reducing alliance-specific route barriers.
