British Airways (BA)

British Airways (BA/BAW) is a full-service network airline based in United Kingdom, founded in 1974. It operates from its hub at LHR, where much of its connecting network is built.

It is a member of oneworld, one of the major global airline alliances, so its frequent-flyer program and network connect with other oneworld carriers — useful when you need a through-ticket or want to earn and use miles across partner airlines.

As a full-service carrier, its fares generally bundle more into the base ticket than a budget airline, but the exact baggage allowance, seat selection and change rules still depend on the fare type you pick, so confirm the conditions of your specific fare before you pay.

When flying British Airways, book under the airline code BA, check the carrier's current baggage, check-in and travel-document rules on its own website, and allow enough time at LHR if you are connecting.
