Let's be really real, travel agents have been a declining business for a long time and that has nothing to do with AI.

The two niches of travel agents that have a future are full service event coordination (group bookings, charter, etc., combined with ground transportation), and complex RTW type bookings ("We're going to fly to Germany, stay two nights, take a train to X, stay a night, fly domestically across Italy, then hop on a river cruise, and fly home from Croatia").

For simpler things, there's just no need and many are their own worst enemy.

I took my family to Maui for 11 nights, spending most of that in a resort, then a night in Hana before heading back and home.

The two agents we spoke to that specialized in Maui vacations quoted us a price through them that was $4,000 more than the hotel wanted for the same room direct, and $7,000 more than through Priceline. Both presented itineraries that were in fairly direct contradiction with some requests we made ("we'd like to do x, y, and z, but each with at least a day between them" - one wanted to book them on three consecutive days "so then you could relax"), etc. And both got fairly pissy when we said didn't feel they were giving us something aligned with what we wanted, nor communicating any reason for doing so. "Good luck booking with Priceline, the hotel is going to give you the worst room they can". While I know that there's maybe some stigma with that, ended up being the opposite, "And you're staying with us for ... oh, eleven nights, lets make sure it's the best room we can give you".
