Definitely the biggest benefit to me is being able to be backed up on alternative flight and being able to easily change that as irregular operations and seating change. This was at one time a benefit for EXP but no more. I generally do my own research during irregular operations and can do just as a good job if not better than any agent. The agent at the boarding gate helps get me around the scrum lining up after preboards but it's only consistent at PHX.
