Why trust this data?

Hand-verified sources

Every fee is checked against the airline's official baggage policy page. Each record includes a "last verified" date and a direct link to the source.

75-airline coverage

Major carriers and budget airlines across North America, Europe, Asia-Pacific, Latin America, and the Middle East. New airlines added as data is verified.

Privacy-friendly

The widget sets no cookies and runs no visitor analytics. A single beacon logs the embedding domain name so we can measure reach. No personal data is collected.

Frequently asked questions

Will this widget slow down my site?

The widget loads inside a lazy-loaded iframe that totals under 50 KB. It makes zero external requests beyond the initial page load, so it will not affect your Core Web Vitals or Lighthouse score.

Does it work on WordPress?

Yes. Open the block editor, add a Custom HTML block, and paste the embed code. The widget renders immediately in the preview and on your published page.

How does the calculator work?

The widget estimates total checked bag fees based on bag count (1-3), trip type (domestic or international), bag weight, and linear dimensions. It applies overweight surcharges for bags over 50 lb and oversize surcharges for bags over 62 linear inches, then sorts all airlines cheapest first.

Will the fee data stay current?

Yes. The widget pulls from a verified database of 75 airlines that is updated regularly. Each record includes a "last verified" date. When we update the data, every embedded widget reflects the change automatically.

Can I customize the colors and defaults?

Yes. The widget supports light and dark themes, a custom accent color via hex code to match your brand, adjustable corner radius, compact mode for sidebar embeds, and default bag count, trip type, and region via URL parameters. Use the customizer on this page to configure all options visually.

Do I need to create an account or pay anything?

No. The widget is completely free with no registration, API keys, or usage limits. The only data collected is the domain name where the widget is embedded, so we can measure reach. Paste the code and it works.

What platforms does it support?

Any platform that allows HTML embeds: WordPress, Squarespace, Ghost, Webflow, Wix (HTML embed widget), Jekyll, Hugo, Astro, Next.js, and static HTML sites.

Can I remove the Powered by Vientapps link?

The attribution link must remain visible. It is a small, unobtrusive footer that helps us fund ongoing data verification and maintenance.
