Google Flights is the fastest way to discover a route and its baseline price, but the price alone is only part of the decision. Three free Chrome extensions — Legrooms+, Points Path, and Seats.aero — layer directly on top of the standard search results, adding seat comfort data, points-vs-cash math, and cross-alliance award availability without leaving the page. Here's how each one works, and the order to use them in.

Start With Google Flights Itself

Before adding any extension, set a solid baseline using Google Flights' own tools. The Date Grid and Price Graph visualize pricing across a whole month, so you can spot the cheapest departure and return combination instead of guessing. The Explore Map does the same thing across destinations instead of dates — useful if you know roughly when you want to travel but haven't picked a city yet.

Whatever price the Date Grid returns for your chosen dates becomes your worst-case scenario: the cash amount you'd pay if none of the three extensions below turn up anything better.

1. Legrooms+ — Comfort Without Leaving the Results Page

A cheap seat that arrives with your knees against the seatback in front of you isn't actually a good deal on a long-haul flight. Legrooms+ adds seat pitch (legroom, in inches and centimeters) and baggage allowance directly under each flight's duration in the Google Flights results list, so you don't have to cross-reference a separate seat-map site for every option.

Use it to filter out anything below your personal comfort threshold — many travelers draw the line around 30 inches of pitch for flights over 5 hours — before you spend time comparing prices on a seat you wouldn't actually want.

2. Points Path — Cash Fare vs. Award Redemption

Deciding whether to pay cash or redeem frequent-flyer miles usually means opening a separate airline app and doing the math yourself. Points Path puts the award price directly next to the cash fare on the same Google Flights row, using live award availability and its own per-program point valuations to recommend whichever option is actually worth more.

It covers most major domestic and international carriers, but only works when Google Flights is set to English (United States) — the extension parses the page's English-language layout to find the fare it needs to compare against.

3. Seats.aero — Finding the Cheapest Partner Redemption

Airlines routinely price their own award seats higher than a partner program would charge for the identical flight. Seats.aero surfaces that gap: it scans over 25 loyalty programs across Star Alliance, oneworld, and SkyTeam, and injects a panel showing which partner program has the seat for fewer points or lower taxes — for example, booking a United flight through Air Canada's Aeroplan program instead of United's own MileagePlus.

This is the deepest layer of the three, and the one that rewards travelers who already hold transferable credit card points (Chase Ultimate Rewards, Amex Membership Rewards, Capital One), since those points can move to whichever program turns out to be cheapest.

The Workflow: How the Three Fit Together

Used one at a time, each extension only tells part of the story. Run them in this order instead:

1. Macro-search on Google Flights — find your cheapest dates with the Date Grid. This sets your baseline cash price.

2. Filter for comfort with Legrooms+ — drop anything under your personal legroom threshold before you invest time comparing the rest.

3. Check the math with Points Path — see whether the airline's own award rate beats paying cash for what's left.

4. Look for a cheaper partner with Seats.aero — before committing to the primary airline's award price, check whether a partner program undercuts it.

5. Book — pay cash directly with the airline if the fare is genuinely low, or transfer your credit card points to whichever program came out ahead.

One Setting to Get Right First

Set Google Flights to English (United States) with currency in USD before turning any of these extensions on. Points Path in particular depends on that exact formatting to parse the page correctly — a different language or currency setting can cause it to silently show nothing at all.

Where FlyTLV Fits In

These three extensions optimize a single search you're actively looking at. FlyTLV solves a different half of the same problem: you set a target price once, and it keeps checking in the background so you find out the moment a fare from Tel Aviv actually drops to it — no need to keep a tab open or re-run the Date Grid every few days.
