They will of course have the ability to control their privacy settings. If a Member prefers not to have their social profiles, contact information, or even their name kept private, they just need to check that box. Other members will be instructed to not bother people who opt to travel incognito.
But Members will be able to selectively reveal any part of their profile information to any other given Member. Thus, all Members have fine-grain control over exposure of their personal information to other Members.
With this arrangement, Members will actually be able to see the profiles of other Members on their flight (subject to those Members privacy settings) so they can be prepared to have productive conversations in flight. They can send them messages directly through the Members Portal do initiate the conversation before the flight. If a Member is marked as ‘Incognito’, the other Members will know not to try and engage that person in conversation.
