Completely agree! Especially considering that flights for most people are still a large expense, people, especially those in the credit card points game, like to go to great lengths to score the cheapest possible flights.
For example, this person[0] could have simply booked a United flight from the United site for 15k points. Instead the person batch emailed Turkish Airlines booking offices, found the Thai office that was willing to make that booking but required bank transfers in Thai baht to pay taxes, made two more phone calls to Turkish Airlines to pay taxes with a credit card, and in the end only spent 7.5k points for the same trip on United.
This may be an extreme example, but it shows the amount of familiarity with the points system, the customer service phone tree and the actual rules to get cheap flights.
If AI can do all of that, it'd be useful. Otherwise I'll stick to manual booking.
