Data verification
Airline policy data is verified against carrier websites monthly. Last full pass: April 2026. When we update the data, every embedded widget reflects the change automatically. The same verified dataset powers the carry-on size checker and checked bag fee tool.
Frequently asked questions
Are these widgets really free?
Yes. No accounts, no API keys, no per-call billing. Every widget is free to embed on any site, including commercial and monetized blogs.
Will the widgets slow down my page?
Each widget is under 50 KB, served from CDN, and lazy-loaded by default. They make no external requests during page load, and optional usage beacons on user interaction are non-blocking, so they will not affect your Core Web Vitals or Lighthouse score.
Do they track my visitors?
No third-party trackers, no cookies, no fingerprinting. We log anonymous usage events (widget loads, key interactions, embedding domain, country, device class) so we can improve coverage. No IP addresses, no personal data, no cross-site identifiers. GDPR-friendly.
Can I use them on a commercial site?
Yes. You can embed these widgets on any site, including monetized blogs, affiliate sites, and client projects. No attribution required, though a link back is appreciated.
How is the data verified?
Airline policy data is verified against carrier websites monthly. Each airline record includes a "last verified" date. When we update the data, every embedded widget reflects the change automatically. The same dataset powers the carry-on size checker and checked bag fee tool on Travel Vient.
What platforms are supported?
