Sync Booking.com and Airbnb: a four-step iCal process

Step 1 – Get your Booking.com iCal calendar link

Booking.com generates one iCal feed per property. Here is where to find it:

Log in to Booking.com Extranet → select your property.
Go to Rates & Availability → Calendar sync.
Click Export calendar (ICS). Copy the URL shown.

Keep it private: the iCal URL shows your reservation dates to anyone who has it. Store it in a password manager and regenerate it if shared by mistake.

Some Booking.com accounts require you to confirm each export — check your Extranet settings to enable automatic exports.

Step 2 – Get your Airbnb iCal calendar link

In your Airbnb host account, open Calendar → Availability.
Click Sync calendars → Export calendar.
Copy the iCal URL. It looks like https://www.airbnb.com/calendar/ical/12345678.ics.

Each Airbnb listing has its own iCal link. If you have multiple listings, repeat this for each one.

Step 3 – Import in both directions

Synchronization must be configured in both directions so each platform receives the other calendar’s unavailable dates. iCal delays still apply.

Airbnb → Booking.com (block Airbnb reservations in Booking)

In Booking.com Extranet → Calendar sync → Add calendar.
Paste your Airbnb iCal URL and confirm.
Booking.com will now block dates reserved on Airbnb.

Booking.com → Airbnb (block Booking reservations in Airbnb)

In Airbnb → Availability → Sync calendars → Import calendar.
Paste your Booking.com iCal URL and save.
Airbnb will now block dates reserved on Booking.com.

Important: iCal sync is not instant. Both Airbnb and Booking.com refresh external calendars every 15–30 minutes. Add a 2–3 hour gap between checkout and next check-in to cover this delay.

Step 4 – Verify the sync and fix propagation issues

Create a manual block on one platform (e.g. block tomorrow on Airbnb).
Wait 20–30 minutes and check the other platform — the date should appear as unavailable.
Delete the block and confirm both platforms show the date as available again.

Sync not working? Re-generate both iCal URLs (old links sometimes expire), delete the existing import and re-add them. Booking.com occasionally requires you to confirm the export again via email.

Common causes of Booking.com ↔ Airbnb sync failures

Expired iCal link — regenerate it in your Booking.com Extranet or Airbnb settings.
Manual export confirmation required — some Booking.com accounts need you to re-confirm the export each time.
Same-day bookings — a 30-minute sync delay can still cause conflicts on the same day. Use a channel manager for real-time sync.
Multiple listings — each listing has its own iCal link. If you have 3 properties, you need 6 connections (3 × Airbnb→Booking + 3 × Booking→Airbnb).

Free tool: preview any iCal link

Paste your Booking.com or Airbnb iCal URL to verify it is working — the preview shows upcoming reservations anonymously through the BNB Pilot backend.

The preview runs through the BNB Pilot backend to bypass CORS restrictions and anonymise the feed.

Skip the manual sync – BNB Pilot does it automatically.

BNB Pilot brings your iCal feeds together and flags detected overlaps. Import cycles and external platform delays still apply.
