I wasn't aware this existed. I recently burned 4+ hours booking my family vacation to Hawaii in 1st. My issue was the hop from Honolulu to Maui. I would have happily paid someone $100 to $150 to do that work for me.
I think it comes down to how much you value your time. The flip side is that someone who is an expert at this can probably do it in under an hour. I I value my time at $50 an hour and it takes me four hours to do this I can end up a net $50 better off hiring someone. If that person's time is also worth $50 an hour and they can do the job in an hour they end up $100 better off. Everyone wins. I'm having flashbacks to my Economics 101 course many years ago.
