Thanks Frat ! So,how are the rosters generally constructed ? I know you have blank days (days free from duty but subject to change - correct ?) that they put in between trips for legality. Therefore, as such, how do the patterns look like ? 7 on - blank - 6 on - blank. Basically what I'm trying to figure out is how many blank days do you normally get in your 18 day rotation and how many days in a row do you fly between blank days.
