Mastercard is launching a new Lounge Key benefits program on April 1, 2025, which will replace the existing program of free entrance to Business Clubs at the airports in Belgrade, Sarajevo, and Vienna.

As part of the new program, Mastercard Premium members* are granted four complimentary entrances to more than 1,500 airport lounges worldwide through the Lounge Key network . The number of complimentary entrances is reset every January 1st, and a list of available locations can be found at www.loungekey.com or via the Lounge Key app.

All you need to do to use this benefit is to present your valid Mastercard premium card in your name to the POS terminal located at the entrance to the Club, after prior registration at www.loungekey.com . Also, if you are traveling with someone, your companions can also access the Business Club, and this cost will be charged directly to you.

Users who have so far enjoyed the benefit of free entry to Business Clubs at the airports in Belgrade, Sarajevo and Vienna **, this option remains available but in a modified format: they will be able to take advantage of two free entries to these exclusive lounges in the period from April 1, 2025 to March 31, 2026, after which this benefit will not be available.

Check which benefit applies to you - the table below lists the BIN numbers (first 6 digits on the card), so you can easily compare the listed BINs with the digits on your card and be sure which Mastercard Premium program benefit you can enjoy.
