I guess I should have clarified my sched. I have 4 days of res the end of Apr. then in May I have a reg line and the first day of May is a day off. There is a five day trip that starts on my first day of res (28 Apr) it ends on 2 May. Icrew wouldn't let me put in a YS for first to fly on res days for the trip because of the spill over to a day off. I am going to fly the 28Apr-1May anyway so I thought I would pick up this trip because it has some good overnights. Plus with mil leave in May I only have about 66 hours. I thought adding some spill over hours would be good. I have the YS in for that trip and another four day trip that covers just the four days of res the end of Apr. I was wondering if the two different types of YS's are run at the same time in preference order. I have the 5 day as preference 1 and the 4 day as preference 2. Hopefully this helps. Thanks for the advice for a newbie.
