How do I stop double bookings between Airbnb and Booking.com?
Last updated:
Short answer
Keep one master calendar that imports the bookings from every platform, and have every platform import that master calendar back. A booking made on Airbnb then blocks the same dates on Booking.com, Vrbo and your own website.
All three platforms support this through iCal calendar links, at no cost. The only gap left is timing: each platform re-reads the calendars it imports on its own schedule, so two bookings made within the same short window can still collide. A minimum advance notice of a day or more closes most of that gap.
Why double bookings happen
Airbnb only knows about Airbnb bookings. Booking.com only knows about Booking.com bookings. Unless something tells each platform what the others have sold, both will happily sell the same night.
Owners usually notice when a second confirmation arrives for dates that are already taken — and then have to cancel one guest, which platforms penalise with fees, lower ranking or both.
The three ways to keep calendars in sync
There are three common set-ups, from simplest to most involved:
- Platform-to-platform iCal links: import Airbnb's calendar into Booking.com and the other way round. Free and fine for two platforms, but every new platform multiplies the links, and your own direct bookings and owner stays live nowhere.
- One master calendar (a hub): every platform's calendar flows into one place, and one feed flows back out to every platform. Free or low cost, and direct bookings, owner stays and closed periods are included.
- A full channel manager with API connections: faster updates and often rate and listing management too, usually priced per listing per month and aimed at professional managers.
How to set up a master calendar with iCal
Whatever tool you use as the hub, the steps are the same:
- Copy each platform's calendar export link — look for “sync calendars”, “export calendar” or “iCal” in the platform's calendar or availability settings.
- Paste each link into your master calendar as an import.
- Copy the master calendar's own export link and add it to each platform as an imported calendar.
- Record direct bookings, owner stays and maintenance in the master calendar only — they reach every platform from there.
- Test it: block a free date in the master calendar, wait for the platforms to refresh, and check the date closes everywhere.
The gap no iCal sync can close
iCal is a pull system: each platform fetches the calendars it imports when it chooses to, typically every few hours, and no owner tool can make it fetch sooner. If two guests book the same dates on two platforms inside that window, both bookings can go through.
In practice this is rare for most holiday rentals, and you can shrink it further:
- Set a minimum advance notice (one or two days) on each platform, so a same-day booking cannot land before the calendars catch up.
- Refresh your master calendar by hand after a booking comes in, instead of waiting for the next automatic sync.
- If you need near-instant blocking across many listings, a paid API channel manager is the right tool.
How Stayem does it
Stayem is a master calendar built for independent owners. It imports your Airbnb, Booking.com, Vrbo and other iCal calendars automatically every hour, with a refresh button for on-demand syncs, and gives you one export feed to add to every platform. Stayem never changes or removes the bookings on your platforms — it only adds its own dates as an extra calendar, so the set-up is reversible.
It is free to start: one property and one calendar, with sync and bookings, stay free.
Common questions
Can Airbnb and Booking.com sync with each other directly?
Yes, through iCal links: each platform can import the other's calendar. It works for two platforms, but it does not include your direct bookings or owner stays, and every extra platform adds more links to maintain.
How often does iCal sync update?
It depends on who is reading the calendar. Each platform re-reads the calendars it imports on its own schedule, often every few hours. Stayem imports every hour and can be refreshed on demand; how quickly a platform picks up Stayem's feed is up to that platform.
Is a channel manager better than iCal?
A channel manager with API connections updates faster and can manage prices and listings, but it usually costs a monthly fee per listing and is built for managers with many properties. For one to a few properties, an iCal master calendar with a minimum advance notice prevents almost all double bookings at little or no cost.
What should I do if a double booking happens anyway?
Contact the platform where the second booking was made straight away and explain it is a calendar-sync conflict; then offer the guest help finding an alternative. Cancelling as the host usually carries a penalty, so act quickly and check your sync links afterwards.
