The “First name” and “Surname” fields are visible to the public and will be your pilot name displayed on our airline. The “Username” field is only used to login to your account. If you do not want to display your first and last name, you may put your Discord/Forum username in the first name field and a random letter in the “Surname” field. You may later edit your profile at fsairlines.net by going to My Account>Edit Profile to delete the the Surname field then click "Edit" to save.
