I have not been able to plan vacations too far ahead. The challenge that I face is then getting 4 tickets on awards. part on rewards and other purchased often does not make sense as the purchased tickets may be more expensive than others available for the same route, and I dont really want to break up the family. Any idea whether they keep on adding availability (so as to not sure more than say 2 tickets at one go), or do they normally show all available reward tickets at the same time.
