Flight Grid Extender

About

See a full month of departure dates against a full month of return dates — in one view.

Google Flights' built-in price grid only shows a small window at a time. Flight Grid Extender adds a "Show 30 days" button to the price-insights dialog that builds a 30x30 departure-by-return price matrix.

FEATURES
  • 30x30 grid of round-trip prices, fetched in parallel (a couple of seconds)
  • Color coding: cheapest, low, normal, and high fares
  • Weekday labels with Friday/Saturday/Sunday highlighting
  • Pinned row and column headers so dates stay visible while you scroll
  • Click any price to rerun the search for that exact departure/return pair

PRIVACY
Collects and transmits no user data. No analytics, no tracking, no remote code. It only issues the same price requests to google.com that the page already makes.
