Google Flights Export

A browser bookmarklet that copies Google Flights booking details to the clipboard as formatted plain text (for chat / notes) and HTML (for email).

Usage

1. Build the bookmarklet (see below) and paste the contents of dist/GoogleFlightsExport.bookmarklet.js as the URL of a new browser bookmark. The file starts with javascript: — use the whole string as-is.
2. Open a Google Flights booking page (the one that lists each segment of the selected itinerary) and click the bookmark.
3. A toast appears ("Copied N flight legs to clipboard") and the result is on your clipboard in both plain-text and HTML flavors. Paste into Gmail and the formatting is preserved; paste into a text editor and the markdown-style *bold* fallback shows.

Example output:

*Etihad EY 146* (dur: 6 hr 15 min)
Departure Geneva Airport (GVA) 12 May 10:45 AM
Arrival Zayed International Airport (AUH) 12 May 7:00 PM

*Etihad EY 800* (dur: 10 hr 10 min)
Departure Zayed International Airport (AUH) 12 May 9:25 PM
Arrival Narita International Airport (NRT) 13 May 12:35 PM

Build

yarn install
yarn build

This produces:

• dist/GoogleFlightsExport.bundle.js — readable IIFE, useful for inspection.
• dist/GoogleFlightsExport.bookmarklet.js — URL-encoded, javascript:-prefixed, ready to paste into a bookmark.

Test

yarn test                  # unit + fixture-based integration (offline)
LIVE=1 yarn test           # also runs the live Google Flights end-to-end test

Live test variants:

# Drive the search flow from scratch (GVA → NRT, 90 days out).
LIVE=1 yarn test tests/bookmarklet-live.test.js

# Or point the test at an existing booking URL in your browser history.
LIVE=1 GFE_TEST_URL="https://www.google.com/travel/flights/booking?tfs=..." \
  yarn test tests/bookmarklet-live.test.js

How it works

The bookmarklet looks for flight-leg containers on Google Flights' booking page using DOM selectors (.c257Jb for each leg, .MX5RWe for the airline/flight number/aircraft, .dPzsIb + .SWFQlc for departure/arrival, .CQYfx for duration). Text from each container is parsed with regex into a structured Leg, then serialized to plain text and HTML. Result is written to the clipboard via navigator.clipboard.write().

When it breaks — and it will, because Google cycles these class names — the fix lives in src/extract.js: update the selectors at the bottom of the file and re-capture a fresh DOM fixture into tests/fixtures/.

Files

• src/GoogleFlightsExport.js — bookmarklet entry point: DOM query + clipboard write + toast.
• src/extract.js — pure extraction and formatting helpers.
• tests/extract.test.js — unit tests for the pure functions.
• tests/bookmarklet.test.js — Playwright integration test against the HTML fixture.
• tests/bookmarklet-live.test.js — live end-to-end test against google.com/travel/flights (opt-in via LIVE=1).
• scripts/build.mjs — esbuild-driven bundler that emits the bookmarklet.
