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 no external requests during page load, and optional usage beacons on user interaction are non-blocking, 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. We log anonymous usage events (widget loads, interactions, embedding domain, country, device class) so we can improve coverage. No cookies, no personal data. 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 line that sits directly below the widget must remain visible. It is a small, unobtrusive credit that helps us fund ongoing data verification and maintenance.
