1. Why you need to sync

If a guest books 15-18 March on Airbnb and those dates are still showing as available on Booking.com, another guest can book the same nights. You then have to cancel one booking, refund the guest, take a cancellation penalty, and potentially lose your Superhost status.

Syncing ensures that when a booking is made on one platform, the dates are blocked on all others. There are two methods: iCal (free but delayed) and channel managers (real-time but paid).

Listing on multiple platforms is worth the effort. Booking.com delivers European and business travellers that Airbnb does not reach. For the full platform comparison, see our guide to Expedia vs Booking.com.

2. Method 1: iCal sync (free)

2.1 Export from Airbnb

1. Go to your Airbnb listing, then Calendar > Availability > Import/Export Calendar.
2. Copy the Export Calendar link (an iCal URL).

2.2 Import into Booking.com

1. Log into your Booking.com Extranet.
2. Go to Rates and Availability > Sync Calendars.
3. Paste the Airbnb iCal URL and save.

2.3 Export from Booking.com and import into Airbnb

1. In the Booking.com Extranet, go to Rates and Availability > Sync Calendars.
2. Copy the Booking.com iCal export URL.
3. In Airbnb, go to Calendar > Availability > Import Calendar and paste the URL.

2.4 Limitations

iCal sync is not real-time. It updates every 1-4 hours depending on the platform. During high-demand periods, a booking can come in on one platform before the other has synced. For a single property with moderate bookings, this is usually fine. For multiple properties or high turnover, use a channel manager.

3. Method 2: channel manager (real-time)

A channel manager connects to Airbnb, Booking.com, and Vrbo via their APIs and syncs availability, rates, and bookings in real time. When a booking comes in on one platform, the others are updated within seconds.

3.1 Popular options

• Guesty: full property management suite. Best for professional operators with 5+ properties.
• Hostaway: strong multi-platform sync with automation features.
• Lodgify: channel manager plus direct booking website builder. Good for hosts who want to reduce platform dependency.
• Beds24: budget-friendly option for 1-3 properties.

3.2 Cost

Channel managers typically cost 15-50 pounds per property per month, depending on features. This is a deductible business expense.

3.3 When to upgrade

If you manage 2+ properties, list on 3+ platforms, or have frequent turnovers, a channel manager saves enough time and prevents enough double-booking disasters to justify the cost.

A property management company includes channel management as part of their service. For more on what that costs, see our guide to costs of running a holiday let. For platform fee comparisons, see our guide to Airbnb hosting fees.

4. Troubleshooting common sync issues

4.1 Double bookings still happening

If you are using iCal and still getting double bookings, the most common causes are:

• Sync delay: iCal can take up to 24 hours to update. If a guest books on Airbnb, the dates may still show as available on Booking.com for several hours. There is no fix for this other than switching to a channel manager.
• Wrong URL: you may have pasted the wrong calendar link. Re-export from each platform and re-import to confirm the URLs are correct.
• One-way sync only: make sure you have set up sync in both directions (Airbnb to Booking.com AND Booking.com to Airbnb). A common mistake is only exporting from one platform.

4.2 Calendar not updating

iCal feeds refresh on a schedule set by the importing platform. Booking.com typically refreshes every few hours. If your calendar appears stale:

• Delete the imported calendar and re-add it with a fresh URL.
• Check that your calendar URL has not changed (some platforms regenerate URLs when you update settings).
• Confirm that the property is active and not snoozed on the exporting platform.

4.3 Blocked dates showing as available

If you manually block dates on Airbnb (for personal use), these should sync to Booking.com via iCal. If they do not, the sync feed may not be refreshing. Manually block the same dates on Booking.com as a safety measure while you troubleshoot.

4.4 Adding a third platform (Vrbo, Expedia)

The same iCal process works for Vrbo and Expedia Group platforms. Export your calendar URL from each platform and import it into every other platform. With three platforms, you need six import connections (each platform imports from the other two). At this point, a channel manager is strongly recommended. For how Expedia Group platforms work, see our guide to Expedia vs Hotels.com.

5. When to let a management company handle it

Calendar sync is one of those tasks that seems simple until it goes wrong. A single double booking costs you a cancelled guest, a potential negative review, and the stress of finding an alternative for someone who has already booked.

Professional management companies use channel managers as standard. They connect your property to Airbnb, Booking.com, Vrbo, and direct booking channels through a single system with real-time sync. You never have to think about calendar management, iCal URLs, or sync delays.

If you list on two or more platforms and value reliability over manual effort, management handles this natively. For details on what management includes, see our guide to Airbnb management fees. For the broader cost picture, see our guide to the costs of running a holiday let.

6. FAQ

How do I sync my Airbnb calendar with Booking.com?

Export your iCal URL from Airbnb (Calendar, Availability, Import/Export), then import it into Booking.com (Property, Rates and Availability, Sync Calendars). Do the same in reverse: export from Booking.com and import into Airbnb. This creates a two-way sync that updates every few hours.

Does iCal sync happen in real time?

No. iCal sync can take up to 24 hours to update, though it typically refreshes every 2-6 hours. For real-time sync, you need a channel manager (Guesty, Hostaway, Lodgify, or similar) that connects via API.

Can I sync Airbnb with Vrbo and Booking.com at the same time?

Yes. Export your calendar URL from each platform and import it into every other platform. With three platforms, you need six connections. At this scale, a channel manager is strongly recommended to avoid complexity and sync delays.

What happens if I get a double booking?

You will need to cancel one booking. On Airbnb, host cancellations trigger a fee, block your calendar for those dates, and damage your search ranking. On Booking.com, cancellations affect your reliability score. Prevention (real-time sync via channel manager) is far better than dealing with the consequences.

Do management companies handle calendar sync?

Yes. Professional management companies use channel managers as standard, providing real-time sync across all platforms. You do not need to manage iCal URLs or worry about sync delays. This is included in the management fee.
