in this case, it is necessary to meet the conditions of purchasing a specific class ticket and becoming an airline member.

1. Buy specific class air tickets: Buying first class or business class air tickets can usually go directly to the airport VIP room. Passengers in these cabins enjoy the right to use the VIP room, including rest, catering and other services.

2. Becoming an airline member: Becoming an elite member of an airline or a senior frequent flyer VIP generally requires a certain number of flights or accumulated points. Members with gold card or above can rest in the VIP room of this airline or alliance, no matter which class they take. This membership usually allows you to bring a fellow friend into the lounge.
