Is it worth to buy live

It is absolutely worth it. You’ll gain a ton of features that aren’t included with the base app: access to the entire Infinite Flight fleet, including future reworks/additions too (the A220 is on its way); live traffic and three servers to fly on, meaning you can join group flights and events with community members from this forum; live air traffic control from trained controllers once you reach the Expert Server; the ability to control on the Training Server—and the Expert Server after you apply for IFATC; and so much more! I’d go for it if I were you—at least try it out for a month and see how you like it. Hope you enjoy it and let us know if you have any questions!
