Delta PMS allows you to manage Airbnb reservation change requests directly from your inbox.
You can review and respond to change requests from your guests, or propose changes to an existing reservation yourself.
Important: Your original booking details will not change until the alteration request is approved.
1. How Airbnb Reservation Changes Work
An Airbnb reservation alteration is a request to change an existing reservation. Depending on who starts the request, there are two ways an alteration request can be created.
Guest-initiated request
Your guest requests a change to their reservation through Airbnb.
Guest → Airbnb → Delta PMS → Host
You can review the requested changes in Delta PMS and choose to Approve or Reject the request.
Host-initiated request
You can propose a change to an existing Airbnb reservation directly from Delta PMS.
Host → Delta PMS → Airbnb → Guest
Your guest reviews the proposed changes through Airbnb and decides whether to approve or reject the request.
In both cases, the original booking remains unchanged until the request is approved.
Request statuses
Every alteration request has a status so you can easily see where it stands.
Status | What it means | Effect on the booking |
Pending | The request is waiting for a response. | The original booking remains unchanged. |
Approved | The proposed changes have been accepted. | The approved changes are applied to the booking. |
Rejected | One party has declined the proposed changes. | The original booking remains unchanged. |
Voided | The request has expired or has been withdrawn by the person who created it. | The original booking remains unchanged. |
Important: Only one alteration request can be active for the same reservation at a time.
When does a request become Voided?
An alteration request becomes Voided when:
The person who created the request withdraws it before the other party responds.
No response is received before the reservation's checkout date.
The deadline is based on the property's local time.
Once a request becomes Voided, it can no longer be approved. If the change is still needed, a new alteration request can be created.
2. Manage Alteration Request Notifications
Delta PMS can notify you whenever there is an update to an Airbnb alteration request.
You can receive these notifications through:
Delta PMS
Email
Both
Each notification channel can be enabled or disabled independently in your notification settings.
Notification settings
Use the screenshot showing “Airbnb - Alteration Request” highlighted in the Notification Settings.
When will you receive a notification?
You will receive a notification when:
A new alteration request is received: Your guest has requested a change to their reservation. The request appears as Pending in Delta PMS.
A request receives a response: You will be notified when a request is Approved, Rejected, or Voided.
Clicking an alteration notification takes you directly to the request details in your inbox, where you can review and respond.
Recommended: Keep at least one notification channel enabled so you do not miss an alteration request. If a request is not answered before the reservation's checkout date, it will expire automatically and become Voided.
3. Create an Alteration Request from Delta PMS
As a host, you can propose changes to an existing Airbnb reservation directly from Delta PMS.
For example, you can propose changes to:
Stay dates
Property
Number of guests
Accommodation rate
Your guest will receive the request through Airbnb and can choose whether to approve or reject it.
Important: The booking will only be updated after your guest approves the request.
Step 1: Open the booking
Go to Unified Inbox and open the conversation for the Airbnb booking you want to change.
Step 2: Select "Change Reservation"
In the Booking Details panel, open the menu and select Change Reservation.
Step 3: Enter the proposed changes
Adjust the booking details you want to change.
Depending on the reservation, you can update:
Property
Stay dates
Number of guests
Accommodation rate
Before sending the request, you can review the updated price so you can see how the proposed changes will affect the booking total.
Step 4: Send the request to your guest
After reviewing the proposed changes, click Request Changes to Guest.
The request will appear in the conversation as a Booking Changes Request card.
The card shows:
The number of changes requested
The current request status
How long the request remains valid
Your guest receives the request through Airbnb.
Step 5: Wait for your guest's response
Your guest can review the proposed changes through Airbnb and choose to Approve or Reject the request.
The request status will be updated in Delta PMS.
If your guest approves the request, the booking is updated automatically.
Before sending a request
Please keep the following in mind:
While your request is Pending, no other alteration request can be created for the same reservation by either you or your guest.
The person who created the request can withdraw it before the other party responds. The request then becomes Voided.
If your guest does not respond before the reservation's checkout date, the request expires automatically and becomes Voided.
You can view the full history of alteration requests by selecting View Changes History in the Booking Details panel.
4. Respond to a Guest's Alteration Request
When your guest requests a change to their Airbnb reservation, the request appears in Delta PMS with a Pending status.
You can open the request from the notification or directly from your inbox, review the proposed changes, and respond.
Approve a request
Select Approve if you accept the proposed changes.
Once approved:
The booking details are updated automatically.
The approved changes, such as new dates or guest count, are applied to the booking.
If the change affects the price, the booking total is recalculated automatically.
Reject a request
Select Reject if you do not accept the proposed changes.
The booking remains unchanged. If a different change is needed, a new alteration request can be created after the current request has been rejected.
Important points when responding
An alteration request can only be responded to before the reservation's checkout date, based on the property's local time.
Only one alteration request can be active for a reservation at a time.
Once the current request is Approved, Rejected, or Voided, a new request can be created.
If the person who created the request withdraws it, the request becomes Voided.
A Voided request cannot be reopened. If the change is still needed, create a new request.
5. What Happens After an Alteration Request Is Approved?
Once an alteration request is approved, Delta PMS automatically updates the booking to match the approved changes.
While the request is still Pending, your original booking details remain unchanged.
Booking details are updated automatically
The approved changes, such as new stay dates, guest count, property, or accommodation rate, are applied to the booking.
No manual editing is required.
The booking total is updated
If the approved changes affect the price, the new booking total is calculated automatically.
The change is recorded
The alteration is recorded in the booking history, so you can review what was changed and when.
Please note: Delta PMS cannot send emails directly to your Airbnb guests because Airbnb does not share guest email addresses. Your guests receive reservation updates through Airbnb.
6. How Approved Changes Affect Payments and Invoices
Some reservation changes can affect the total price, such as:
Extending or shortening the stay
Increasing or decreasing the number of guests
Changing the accommodation rate
When an approved change affects the price, Delta PMS automatically recalculates the booking.
While the alteration request is still Pending, the existing payment information remains unchanged.
The booking total is recalculated
The new total is calculated automatically based on the approved changes.
An updated invoice is issued
A new invoice is created with the updated total and is marked as an amendment so that you can distinguish it from the original invoice.
Existing payments are carried over
Any payments your guest has already made are automatically applied to the updated invoice.
You do not need to manually re-enter or move existing payments.
7. What Happens If an Alteration Request Expires or Is Voided?
Not every alteration request ends with a decision.
A request may become Voided if it is withdrawn by the person who created it or if no response is received before the reservation's checkout date.
When a request becomes Voided:
The request is closed and can no longer be approved.
No changes are applied to the booking.
The original booking remains unchanged.
A new alteration request can be created if the change is still needed.
If no response is received
If the request is not answered before the reservation's checkout date, it expires automatically and becomes Voided.
If the request is withdrawn
The person who created the request can withdraw it before the other party responds. The request then becomes Voided.
What this means for you
You will receive a status update when an alteration request becomes Voided, provided the relevant notification channel is enabled.
A Voided request cannot be reopened or approved.
If the change is still needed, either you or your guest can create a new alteration request for the same reservation.
