- We encourage everyone to use the suggested aircraft & airlines listed above for each route.
- As always, expert server pilots are required to comply with IFATC and to follow ALL expert server rules. Failure to comply with ES rules will result in violations being issued.
- Delays are likely, especially during peak hours. Expert Server ATC might send arriving traffic into holding patterns to effectively manage high volumes of traffic.
- Most importantly… Have a great time and share your screenshots with us on social media!
