### What are OTA Virtual Interlines?[​](#what-are-ota-virtual-interlines "Direct link to What are OTA Virtual Interlines?")

There is another way for users to book flight connections that aren’t on a shared ticket (so, no airline alliance), but offer a bit more protection than non-protected transfers. These are called **self-transfer flights** or **OTA virtual interlines**.

Self-transfer flights are booked by an OTA. That means that, although the airlines won't be able to help if a users flights get delayed or cancelled, the OTA will. So, as soon as a problem occurs, the user must contact the OTA so they can help you with rebooking the flight or flights.

#### Important things to know about OTA Virtual Interlines:[​](#important-things-to-know-about-ota-virtual-interlines "Direct link to Important things to know about OTA Virtual Interlines:")

-   The user must also **collect their hold baggage** and check in again for their second flight
-   An OTA will assist the user if anything goes wrong, HOWEVER, different travel agents offer different levels of assistance

Skyscanner has no control over the OTA’s conditions. Even if the OTA offers some protection for a user, we still ask you to make it clear to the user the risks involved with this ticket type.
