British Airways is the flag carrier airline of the United Kingdom which is based and headquartered in Waterside, near its main hub at London Heathrow Airport. Its second hub is London Gatwick Airport and its third hub, served through its fully owned subsidiary, BA CityFlyer, is London City Airport. British Airways is the largest airline in the UK based on fleet size, international flights and international destinations.

British Airways serves nearly 150 destinations, including six domestic.

British Airways fleet consists of 233 aircraft and the airline operates both Airbus and Boeing planes.

The Executive Club is British Airways' main frequent flyer programme. It is part of the network of frequent flyer programmes in the Oneworld alliance. The Executive Club has three tiers of membership: Blue, Silver, Gold. The benefits of the Silver and Gold cards include access to airport lounges and dedicated reservation lines. Unlike most airlines' frequent flyer programmes, the Executive Club keeps separate account of the redeemable BA Miles and the loyalty Tier Points. Flying in higher Classes of Service, i.e. Premium Economy, Business or First, will earn extra BA Miles and Tier Points. As of August 2009, Tier Points can be earned on any flight, including discounted economy fares.
