TravelArrow Flight Price Comparison: How It Works

The problem it solves

Here's something most travelers learn the hard way: the price you see for a flight on one website is rarely the only price that exists. The exact same seat on the exact same flight can cost different amounts on Expedia, Kayak, Skyscanner, and the airline's own site. Google Flights is great, but as travel writers have pointed out for years, it doesn't always surface the cheapest fare — especially since some airlines don't share all their prices with every aggregator.

The traditional fix is miserable: open the same search on five different sites, retype your dates and airports each time, and squint at the results. TravelArrow's flight comparison feature exists to delete that chore.

How the one-click transfer works

You're browsing flights somewhere — say Expedia — and you've found a route you like. Instead of copying the details over to Kayak manually, you click the TravelArrow icon. The extension reads your current search (route, dates, travelers, cabin) and opens that identical search on Kayak and Skyscanner. One click, zero retyping.

Why those two? Because Kayak and Skyscanner are aggregators that often surface fares the site you're on doesn't show. The extension's own description puts it bluntly: travel aggregators often have the cheapest flight deals, so converting your search to them is the fastest way to check you're not overpaying.

The Google Flights upgrades

TravelArrow also improves Google Flights itself. It adds columns to your search results showing the aircraft model and the legroom for each option — small details that matter a lot on a long flight, and that Google doesn't show by default. Users consistently name this one of their favorite touches: picking the roomier plane takes seconds instead of a separate research session.

What it won't do

A few honest limits. It doesn't search every airline on earth — notably, Southwest is mentioned as covered in some descriptions, but ultra-low-cost carriers that don't share fares with aggregators may still slip through. Prices can also shift between the moment you see them and the moment you book, because the extension hands you off to the booking site rather than selling the ticket itself. And like any comparison tool, it's only as good as the sites it checks — which is why pairing it with a quick manual glance at the airline's own site is still smart for big purchases.
