I have a trip that is a single leg of shuttle that blocks in early in the morning. If there was a trip in open time that begins the same day, would day 1 of the 2nd trip just add to the block time of that 1st trip, or would I get the 5:15 guarantee for the only leg of the 1st trip, then a minimum of another 5:15 for day 1 of the follow-on trip? IE, can I snag a 10:30 day?
