I am not quite sure you are comparing apples. The 18 hour long call referred to in this thread is the time you have to report after the company notifies you off a trip assignment. How long is your min time to report after notification at Frontier? 18 hours means when you sit down to dinner at 6 PM you know the company can’t use you until noon the next day. The other good thing is you have no obligation to be phone available. You need only check your schedule or messages often enough to insure you can report in any 18 hour rolling time frame. If you need 4 hours to report you need only check messages or your schedule every 14 hours.
