Question. Ihave two pay back days I want to use. I would like to put them on a four day I have. The four day has 1:20 flying on the first day, nothing on the second, 5:30 on the third and 6:00 on the fourth. The total trip credit is almost 19. All the days have coverage and are blue. If I put the pb days on the last two days the trip I would get almost all credit minus first day. Is that correct. Thanks
