Ocean Alliance welcomes applications, as long as there is a reasonable link to one or more current members. Being a member in Ocean Alliance means that one supports another. There is the need for communication via the Internal forum. The goal is to connect the member airlines in the best possible way to create a reasonable network.

There are some minimum criteria:
- The fleet age should not be over 20 years, better not be over 15 years
- Direct competitors of existing member airlines are not allowed to join the alliance
- You should be ready for an active work-together with the member airlines
