+  Some player flights may be delayed to start. For such flights, it will not be
+  possible to enter the cockpit for a delayed flight until its mission start
+  time, shown in the flight information window.
+</p>
+
+<p>
+  To reduce delays, schedule packages with player flights with an earlier TOT.
+  Note that if some flights within the package will take a long time to reach the
+  target, a player flight may still be delayed.
+</p>
+
+<p>
+  To avoid delays entirely, use the "Never delay player flights" option in the
+  mission generation settings. Note that this will <strong>not</strong> adjust
+  the timing of your mission; this option only allows you to wait in the
+  cockpit.
