Kayak's skill for the Amazon Echo, which enables users to search for flights, hotel and rental cars and book hotel rooms, has added a new trick to its arsenal: flight notifications.

Saying the invocation name "ask Kayak," users can ask Alexa for a flight's status, a notification when a flight lands, or a notification at a specific time before a flight lands.

For instance, a user could ask, "Alexa, ask Kayak to notify me 30 minutes before Flight 123 lands," or "Alexa, ask Kayak for the status of Flight 123."

Users must enable notifications from Kayak through the Alexa app.
