| Non-conformity |
Insufficient semantic structure |
Some content lacks the appropriate structure or semantic roles (ARIA landmarks, headings, etc.), which makes it difficult for assistive technologies to understand. |
| Non-conformity |
Incorrect labelling of components |
Certain interface elements (forms, buttons, links) have accessible labels that are misaligned with their visual information, which can confuse screen reader users. |
| Non-conformity |
Keyboard navigation and focus |
A "Skip to main content" link is not provided on the page and in some components (e.g. header menu) the visual focus indicator is not visible when navigating with a keyboard. In addition, in certain interactions, the screen reader's focus shifts unexpectedly when content changes, which can disorient visually impaired users. |

Flight Search form (keyboard trap) |
The Cheap Flights search engine has keyboard traps: when the keyboard is the sole navigation method, the focus gets stuck inside the form with no easy way out. This prevents keyboard-only users from completing tasks autonomously. |
| Non-conformity |
Images without the correct alt text |
Some images lack equivalent alt text or don't accurately reflect their content, so users who can't see them don't understand the information conveyed. |
| Non-conformity |
Insufficient colour contrast |
In certain texts and graphics, the contrast ratio between the text and the background is less than the minimum required (4.5:1), making it difficult for people with low vision or colour blindness to read them. For example, the contrast is too low in hover state for some links in the headers and footers. |
| Disproportionate burden |
Older videos with no audio description |
Some of the videos published in the past lack audio description. Imbedding audio descriptions in all of this older audiovisual content would demand a disproportionate effort, so it may not be fully accessible to visually impaired users. |
