What is a hotel's best available rate?
Best available rate is the lowest price a hotel is offering for a room tonight, or any given night. This cheat sheet covers how to think about it and what to check before you book. The detail is further down.
How to think about it
- It's the lowest public price. BAR is the lowest unrestricted public rate for a room, with no code or affiliation needed.
- It moves. The rate can change from one night to the next with supply and demand, and is often adjusted in real time based on occupancy.
- It's the benchmark. Negotiated corporate rates are measured against BAR and are set to sit below it.
- Groups move it too. A hotel's best available rate drops significantly if you book with a large group.
What to check
- The corporate rate still wins. Corporate rates are not cheaper than public rates on every date, so verify prices before booking.
- The whole stay, not just the night. Inclusions like breakfast, parking and flexible cancellation can outweigh a small nightly discount.
- The cancellation terms. Confirm the room and cancellation terms shown at checkout before you complete the booking.
Best available rate vs. other hotel rates
| Rate | Who can book it | What sets it |
|---|---|---|
| Best available rate | Any guest | Supply and demand, night by night |
| Qualified rate | Guests in a partner affiliation or loyalty program | A hotel offer, which may be limited to certain packages or rooms |
| Corporate rate | Travelers at a company with an agreement, using its rate code | Negotiation on expected room nights and booking patterns |
| Group rate | Large bookings, typically nine or more rooms | A discount for the size of the booking |
How it works on Engine
On Engine, you review the pricing summary, property terms and cancellation terms before you complete a hotel booking. Admins can add lodging rate caps to travel policies, with limits by location, and choose whether an out-of-policy room is not allowed, allowed with a reason or allowed with approval.
Questions
What does BAR mean in a hotel?
BAR stands for best available rate, the lowest rate offered for a room at a given time. Hotels often adjust it in real time based on occupancy levels and demand.
Why does the best available rate change?
It follows supply and demand, so it can fluctuate from one night to the next.
Is a corporate rate always lower than BAR?
Corporate rates are set to sit below BAR, but they are not cheaper on every date. Many companies set up rates with a hotel and never check that they are still getting the best deal.
What is the difference between BAR and a qualified rate?
BAR is open to any guest. A qualified rate is a discount or offer only available to guests in a partner affiliation or loyalty program, and hotels may limit it to certain packages or rooms.
