Priority fixes for wizzair.com
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
Offscreen images lazy-loaded
Observed: The homepage had 30 images and none used loading="lazy".
Why it matters: Images below the fold are only downloaded when the visitor scrolls near them, which frees bandwidth for what is visible first.
What to do: Add loading="lazy" to images below the fold. Do not lazy-load the main hero image, because that delays the largest visible element.
50% of Airlines peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.
Priority 2 · Harden
Certificate lifetime of 100 days or less
Observed: The certificate from Amazon had a 394-day validity period, longer than the 100-day maximum that applies from March 2027.
What to do: Move to automated issuance and renewal now, while you still have time to test it.
39% of Airlines peers do this.
Priority 3 · Accelerate
HTTP/3 advertised
Observed: The homepage did not advertise HTTP/3 through an Alt-Svc header.
What to do: Turn on HTTP/3 at your CDN. Browsers fall back to HTTP/2 automatically, so the risk is low.
On Amazon CloudFront: Select HTTP/3 in the distribution's supported HTTP versions.
16% of Airlines peers do this.
Priority 4 · Harden
CAA records limit who can issue certificates
Observed: No CAA record was found for wizzair.com, so any public certificate authority may issue for it.
What to do: Publish CAA records naming every CA you actually use, including the CAs your CDN uses for managed certificates. Add an iodef contact if you want reports.
9.9% of Airlines peers do this.
