The airline
Virelia Airways operates inside Roblox at Banja Luka International Airport (LQBK). There are no scheduled flights. A flight exists only while the crew has check-in open for that session.
Check-in
You connect the Roblox account you spawn with, choose Economy or Business, and receive a seat for that flight. The boarding pass is for the game. It is not a ticket on a real aircraft. There is no first class.
Your account
Allowing Virelia Airways lets the desk read your Roblox username so the seat can be issued in that name. You can disconnect the account from the profile menu. Roblox can also revoke the app from your Roblox settings.
