The **best available rate (BAR)** is the lowest publicly available, usually flexible, price a hotel offers for a room on a given night, without conditions like prepayment, membership or packages. It moves with demand and is often the reference for other rates (for example, non-refundable at BAR minus 10%).

## BAR and AI agents

When an agent compares a hotel's own website with OTAs, it is usually comparing public, unconditional prices, close to BAR. Discounts the agent can't see, such as member rates behind a login or codes in a pop-up, don't count in that comparison. If BAR on the hotel's site is the same as on an OTA, the agent tends to choose whichever is easier to complete.

## Why it matters for AI visibility

If AI can only see an OTA's rate, it quotes and links that rate. Your own visible rate keeps the recommendation pointing to you.
