Quite impressed with lola's ability to provide travel recommendations. It uses both AI and human travel agents to provide flights, hotels, and other travel services. My brother recently travelled to China and Japan with a complex itinerary/requirements. For a first experience, he saved so much time booking through lola. If you value your time, I'd check it out. Flight bookings cost a flat fee, but everything else is free. The experience gets even better starting your second booking!
