From previous experience operating out of Montreal, your flights to Las Vegas, Dallas, and Los Angeles will not be very successful. You’ll have far more success with regional domestic flights from Montreal. Cyberairlines and AirlineSim are very different games, so please make sure to read up as much as possible on guides and forum posts. Lastly, you’ll need to have a successful, profitable airline with a AAA financial rating that has operated for at least a few weeks if not a few months before top alliances will be willing to accept you. It’s not easy, but the outcome is very rewarding. Stick with it and you’ll see results.
