Free Tools

Flight Comparison Tools

Free utilities to plan, compare, and check the fine print on US flights.

How our tools work

Free, independent, and built to save you money — not to sell you anything.

Independent data. We pull fare data from our booking partner Travelpayouts and from airline websites directly. We don’t take kickbacks to promote specific airlines — the cheapest result wins, whoever is selling it. That’s the whole reason the tools exist.

Free forever. Every tool on this page is free and always will be. We earn a small commission when a reader clicks through to a booking site and buys a flight. That funds the rest of the site — you never pay us.

Privacy-first. We don’t collect email addresses, run accounts, or store personal data on this site. Affiliate clicks pass anonymous referral IDs to booking partners and that’s it — no profile, no tracking pixels, no signup wall.

Tools FAQ

The most common questions about our free flight tools.

Are the tools really free?

Yes. Every tool on this page is free with no sign-up required and no premium tier. We earn from affiliate links when you book through partner sites — never from your data.

Do you sell or share my data?

No. We don’t collect email addresses, accounts, or personal data on this site — there’s nothing to sell. Affiliate clicks pass anonymous referral identifiers to booking partners, nothing more.

Why don’t you offer price alerts?

We deliberately don’t collect email addresses. Reliable alerts mean storing personal data and processing unsubscribes — all of which is at odds with the lightweight, no-tracking site we want to run. Most major US airlines run their own free fare alerts on their websites — sign up directly with the carrier and use them alongside our explore map and fare finder.

How accurate is the live flight tracker?

Status data comes from aviation feeds that update every 15–60 seconds. Accuracy is typically within 2–3 minutes of the airport’s own display boards. For boarding and gate information, we recommend double-checking with the airline within an hour of departure.

Can I use the compensation calculator for any airline?

The DOT calculator covers any flight that touches the United States — departing, arriving, or operated by a US carrier. The 2024 DOT auto-refund rule applies to cancellations and significant changes; bumping pay under 14 CFR 250 applies to involuntary denied boardings on US carriers. International flights operated entirely by foreign carriers between non-US points fall under the laws of those jurisdictions, not DOT.
