British Airways was a founding member of the oneworld alliance, which was launched in 1999 by American Airlines, British Airways, Cathay Pacific and Qantas.
The alliance has since grown with Finnair and Iberia joining in 1999, LAN in 2000, Japan Airlines and Royal Jordanian in 2007, S7 Airlines in 2010, airberlin in 2012, Malaysia Airlines and Qatar Airways in 2013, and TAM Airlines, US Airways and Sri Lankan Airlines in 2014.
The oneworld alliance brings 15 of the world's leading airlines and around 30 affiliated carriers. Together, these airlines operate more than 14,000 daily flights to some 1,000 destinations across the globe.
British Airways Executive Club members can collect and spend Avios on eligible oneworld flights, and use their rewards and privileges throughout the alliance. oneworld was the first global alliance to introduce interline ticketing between member airlines, which means smooth transfers and greater flexibility across the entire network, and offers the widest range of alliance fares, making it easier to travel throughout its global network.
British Airways currently operates two joint businesses which enable the airline to give more choice to its customers. British Airways launched its transatlantic joint business with Iberia and American Airlines on October 1, 2010.
The agreement allows British Airways and Iberia to work more closely with American Airlines on flights between North America and Europe. It is a revenue sharing agreement under which member airlines have permission to co-ordinate schedules and pricing on North Atlantic routes.
Customers benefit from more than 1,000 flat beds each way, each day between New York and London. They are able to mix and match airlines and book, through one easy transaction, the best options for them to suit their budget and for their convenience. Airlines co-ordinate their timetables to improve schedules for customers.
Lounge, check-in and baggage privileges for loyalty scheme members are co-ordinated and there are more opportunities to collect frequent flyer points and to spend them across the joint business airlines. It leads to opportunities for all the airlines to take advantage of higher customer volumes to expand into new and existing markets.
In October 2012 British Airways entered into a Siberian joint business with Japan Airlines (JAL) on routes between Europe and Japan. In April 2014, Finnair entered into the joint business agreement between Japan Airlines and British Airways on flights between Japan and Europe.
In 2014, British Airways and Iberia's transatlantic joint business with American Airlines was extended to include American's merger partner, US Airways.
The Atlantic joint business now includes all scheduled flights operated by American and US Airways, British Airways, Iberia and Finnair between North America and Europe.
The stream of traffic from more than 240 destinations in North America will allow customers to flow quickly and smoothly through American and US Airways' nine hubs (New York's JFK, Miami, Chicago, Dallas/Fort Worth, Los Angeles, Phoenix, Charlotte, Philadelphia and Washington DC) to cross the Atlantic to Europe on one of the five airlines.
