Flight Ads - Events

Updated: Feb 4, 2026

Flight Ads uses four events. Every event has a set of parameters, see event parameter details. Use the Meta Pixel on your website, and mobile app events in your Android app and iOS app.

Event	When to Fire	Code Sample
`Search`	On the flight search results page	Pixel, Android, iOS
`ViewContent`	When the user has selected the flight(s)	Pixel, Android, iOS
`InitiateCheckout`	When the user enters the payment screen	Pixel, Android, iOS
`Purchase`	On the booking confirmed page	Pixel, Android, iOS

Meta Pixel for Websites

This guide assumes you already have a Meta Pixel installed. If not, see Using Marketing API with the Meta Pixel.

Make sure the pixel base code is already loaded when you fire an event. If you use a tag manager, make sure you include the tag that contains the pixel code on every page. The tag should appear before the tag that contains the pixel event code. Use the Meta Pixel Helper to validate your pixel implementation.
