Browser Extension Overview

Overview

The MileIntel browser extension puts your loyalty data where you need it — right on the flight booking pages you're already using. Instead of switching between MileIntel and Google Flights to compare options, the extension overlays your wallet balances, point valuations, and Best Path recommendations directly on the search results.

What It Does

• Google Flights integration. See point values and wallet comparisons alongside every flight result. MileIntel calculates whether cash, miles, or transfer partner redemptions give you the best deal.
• Airline website support. On supported airline sites (United, Delta, American, and more), the extension highlights upgrade availability and shows your balance for that program.
• Quick wallet access. Click the extension icon to see your loyalty balances without leaving the page.
• Trip detection. When you complete a booking on a supported site, the extension can auto-create a trip in MileIntel.

Key Details

• The extension works in Chrome and Chromium-based browsers (Edge, Brave, Arc).
• It requires a MileIntel account — sign in via Google OAuth from the extension popup.
• Your data syncs with the MileIntel web app in real time. Changes you make on either side are reflected instantly.
• The extension adds no trackers and only activates on travel-related sites.

Tips

1. Pin the extension to your Chrome toolbar for quick wallet access. Right-click the extension icon > Pin.
