Read this first : CrewLounge CONNECT versus FRIENDS
How to invite a Friend
Users of the CrewLounge FRIENDS app cannot send out requests to a pilot or cabin attendant for "roster follow" by themselves. They must be invited by the aviator.
Pilots and Cabin attendants using CrewLounge CONNECT can share an invitation link to a friend from the Roster Share page. This can be done through the QR Code or by sending a weblink.
As soon as the friend opens the link, a formal request is sent to the CrewLounge CONNECT app of the aviator. The aviator must approve the request.
