Hi! I see you’re having an error when trying to book an Air Serbia ticket using Microsoft Edge on Windows 11. To better help you, could you please provide a bit more detail? For example:

- What exactly does the error message say?
- At what stage of booking does this error happen (searching flights, payment, confirmation)?
- Have you tried any troubleshooting steps so far, like refreshing the page or clearing the browser cache?

Meanwhile, here’s a simple way to start fixing this:

1. Clear your Microsoft Edge cache and cookies:
- Click the three dots (menu) at the top right → Settings → Privacy, search, and services → Clear browsing data → Choose “Cached images and files” and “Cookies and other site data” → Clear now.

2. Disable any browser extensions temporarily, as they might interfere with booking.

3. Make sure Microsoft Edge is updated to the latest version: Menu → Help and feedback → About Microsoft Edge.

4. Try using an InPrivate window (Ctrl + Shift + N) to rule out issues with your current browsing session.

5. Check your internet connection to ensure there’s no interruption.

If after these steps you still see the “errore di downline” (which sounds like a connection or data retrieval error during the booking process), it might be related to server-side issues or a browser permission problem. One specific thing I found in an Air Serbia user guide is to allow pop-ups and redirects for the booking site, as sometimes blocking these can cause booking errors in Edge:

- Go to Edge Settings → Cookies and Site Permissions → Pop-ups and redirects → Add this URL to allowed sites: https://ju.tap.andie.aero/#/

Try this and let me know if it resolves your issue or what the error says now. I’m here to assist you through every step!
