TAP Air Portugal (TP)

TAP Air Portugal (TP/TAP) is a full-service network airline based in Portugal, founded in 1945. It operates from its hub at LIS, where much of its connecting network is built.

It is a member of Star Alliance, one of the major global airline alliances, so its frequent-flyer program and network connect with other Star Alliance 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 TAP Air Portugal, book under the airline code TP, check the carrier's current baggage, check-in and travel-document rules on its own website, and allow enough time at LIS if you are connecting.
