Agoda is an online travel agency. It lists hotels, homes, and flights that a person can search by city and dates, then book on Agoda. The company is part of Booking Holdings, and the stays come from hotels and other property partners, not from Agoda operating those buildings.
A listing shows the room type, the dates, and the cancellation rule that property has set. Prices and what is included, such as breakfast or a free cancellation window, change with the dates and the rate the property is selling. Flight results, where Agoda shows them, are separate from the room.
The useful check is the rate details before payment: whether the price is refundable, and whether the stay is prepaid. Those rules are the property’s or the airline’s, and they are written on the booking page.
