High Impact+25 points estimated

Why It Matters

Render-blocking scripts delay First Contentful Paint by 2.97 seconds, severely impacting user experience.

How to Fix

Move non-critical JavaScript files to load asynchronously using async or defer attributes. Inline critical JavaScript directly in HTML. Load TailwindCSS and validation scripts after initial page render using dynamic imports or script scheduling.

AI Performance Analysis

This Arabic website has poor performance with a score of 46/100, indicating significant user experience issues. The biggest problem is excessive JavaScript execution taking 1.7 seconds, which is blocking the main thread and causing a painfully slow 12.5-second Largest Contentful Paint - users will likely abandon the page before it finishes loading. The site is loading massive amounts of unused code, including 98% unused Font Awesome CSS and oversized images that are much larger than their display dimensions. Reducing JavaScript payloads, optimizing images to proper sizes, and implementing better caching could potentially improve the score by 30+ points and dramatically enhance user experience.

How to Fix:

Split large JavaScript bundles into smaller chunks using code splitting. Remove unused JavaScript from TailwindCSS (28% unused) and Swiper library (61% unused). Implement tree shaking to eliminate dead code and reduce bundle sizes from 130KB to under 50KB.

How to Fix:

Resize the American Airlines logo from 4096x1518 to actual display size of 227x84. Convert PNG images to WebP format for 30-50% size reduction. Add explicit width and height attributes to prevent layout shifts and improve CLS score.
