open their own lounges for cardholders. Pay-per-use lounges Private companies, such as Airport Dimensions by Collinson Group, Aspire Lounges by Swissport, Plaza Premium Lounge, and Global Lounge Network, also operate generic pay-per-use lounges. In contrast to airline lounges, these facilities are open to any traveller traversing the airport, regardless of class of ticket or airline, subject to payment of a fee. Most only offer day passes, but some also offer yearly and lifetime memberships. Access to the lounges can be booked via online platforms such as LoungeBuddy or, in limited cases, one-day passes can be purchased directly at the lounge entrance.

In most cases, airlines will offer first class passengers a free pass to their standard airport club.

Membership fees are sometimes discounted for elite members of an airline's frequent flyer program and may often be paid using miles.

Lounge access can also be attained with an airline status card, which is common in Europe. The top frequent-flyer levels often offer access to any of an airline's lounges or partner airlines' lounges, when traveling in any class of travel
