- Inactivity time is defined as the number of days since the last time you've logged into an airline (the airline itself, not just your forum account).
- If your airline flies at least 1 route, the inactivity period is 21 days. Otherwise, it is 2 days (or 1 day if the world is full).
- Airlines inactive for more than the above number of days are subject to deletion without warning.
These warnings are sent as a courtesy only and do not change the inactivity policy. Not receiving a warning (because your PM system is disabled, your account is not validated, or other reasons) after 21 days does NOT prevent your airlines from being deleted for inactivity - that is still your responsibility.
Also, airlines with 0 routes and very few or no aircraft will NOT receive a warning or grace period before deletion.
If you have special circumstances and know you will be gone for more than 3 weeks (long vacation, etc) and want to keep your airline past the 21 day inactivity limit, you can send me a PM to request an extension.
