1. Can only speak for myself. Have been extended once earlier this year (1 day). Usually a couple of attempts but they have been due to delays of arriving aircraft.
2. My experience. Haven’t been imputed for several years. Others may differ.
3. Fleet type request may be asked during initial call-up and/or interview which may have changed? Otherwise offered upon CJO based on current needs and your experience somewhat. No rhyme or reason at times. Hit or miss. New hires chime in for the latest and greatest.

We probably are desperado currently.
