# What is in-flight mode?

### Overview

In-flight mode allows you to **monitor and optimize** your campaign while it is running.

You can access **live results** on your brand KPIs, compare performance across **creatives, channels, audiences** and make adjustments before the campaign ends.

Once the campaign is completed, a **consolidated report brings together all results in one place.**

### Requirements

To activate **In-flight mode**, the campaign must meet the following condition:

* The campaign must start the day you're doing the setup or in the future, and last a minimum of 10 days.

In-flight Mode **cannot be enabled** if:

* The campaign has already ended
* The campaign has already started, even a few days ago
* The campaign lasts over 90 days.&#x20;

### What you can monitor

With In-flight mode, you can track **Brand lift performance indicators on a daily basis**, including:

* Delivery performance indicators (such as **Ad Recall**)
* Creative diagnostics (such as **Interest, Likeability, Clarity**)
* Brand impact KPIs (such as **Brand Image, Consideration, Purchase Intent**)

In total, the platform allows you to monitor **20+ brand KPIs** throughout the campaign.

Results are updated progressively as new respondents are collected.

### What you can analyze

In-flight mode allows you to compare performance across multiple campaign dimensions:

* **Channels** — identify which media channels drive the strongest impact
* **Creatives** — compare different creatives within the same campaign
* **Audiences** — evaluate performance across audience segments

This makes it possible to identify early performance signals and optimize before the campaign ends.

### Typical use cases

In-flight mode is particularly useful for:

**Multi-channel campaigns**\
Compare performance across multiple media channels to identify the most effective ones.

**Multi-creative campaigns**\
Measure how different creatives perform and identify the most impactful assets.

**Multi-target campaigns**\
Evaluate performance across audience segments and detect underperforming targets.

**Single-channel campaigns**\
Track performance and creative impact, with early insights even if adjustments are limited.

**Offline campaigns**\
Monitor brand impact and get early visibility, even without live optimizations.<br>

### Why use In-flight mode

Traditional Brand lift studies provide results after the campaign ends.

In-flight mode enables advertisers to track campaign impact continuously, helping them:

* Monitor campaign performance trends
* Identify strong or weak media components
* Understand performance differences across audiences or creatives
* Prepare post-campaign optimization strategies

### The difference between In-flight mode and Post- Campaign

The main difference resides in the **timing** :&#x20;

* With Post-campaign, you optimize your future campaigns. 

* With In-flight mode, you can act **while the campaign is running and use the final results** to optimize your future campaigns
