Sync Airbnb, Booking.com & VRBO Into One Calendar

If you list a place on more than one site, every channel keeps its own calendar — Airbnb here, Booking.com there, VRBO somewhere else. A guest books on one and the others don't find out until you remember to block the dates by hand. That gap is how double-bookings happen. iCal Merge pulls every channel's calendar into one feed so you can see all your reservations in a single view.

The double-booking problem

Each platform — Airbnb, Booking.com, VRBO, Expedia, Abritel, Landfolk, Plumguide, and the rest — publishes its bookings as an iCal feed. On their own they don't talk to each other. Merging them gives you one calendar where every booked date shows up, no matter which site it came from, so you can spot a clash before it becomes a problem.

Step 1: Export the calendar from each channel

Every booking site has an "export calendar" or "iCal link" option in its calendar settings. On Airbnb it's under Availability → Connect calendars → Export calendar; Booking.com, VRBO, and Expedia have the same idea under their calendar or sync settings. Copy the iCal/ICS link for each listing. New to these links? The iCal feed explainer covers where to find them.

Step 2: Add each channel as a source

Create a calendar in iCal Merge and paste each link in as a source — one for Airbnb, one for Booking.com, one for VRBO, and so on. There's no fixed list of supported sites; if the channel hands you an ICS link, it works. Each booking gets prefixed with the source name, so at a glance you can tell which platform a reservation came from.

Step 3: Subscribe to your one combined feed

iCal Merge gives you a single link with every reservation from every channel. Subscribe to it in Google, Apple, or Outlook and it stays up to date on its own — when a new booking lands on any platform, it appears in your merged calendar automatically. No app to install, nothing to update by hand.

Read-only by design

iCal Merge is a read-only view, not a channel manager. It doesn't push blocked dates back to Airbnb or Booking.com, so it won't close the booking loop the way a paid property-management tool does. What it gives you — for free, with no account on the guest's end — is one reliable place to see everything that's booked across all your channels at once.

Running more than one property?

If you manage several units or a whole building, give each property its own merged calendar — one per unit, each combining that unit's Airbnb, Booking.com and VRBO feeds — or pull every unit into a single master calendar for an at-a-glance view of the entire portfolio. There's no limit on sources.

A quick tip

If a channel hands you a link starting with webcal://, change it to https:// before adding it — it's the same feed, just the address iCal Merge expects.
