Create a flat-style SVG illustration for a Reddit ad about flight delay compensation. Scene: a passenger jet banking through the sky, viewed from a slight angle, flying above and through layered clouds at different depths and opacities for a sense of scale. The plane should be a clean, simplified silhouette in white with light blue-gray accents on the wings/tail (no photorealism, no gradients on the plane itself). Background: a vertical sky gradient from deep blue at the top to soft pale blue near the bottom. Add a few thin white motion-trail lines behind the plane to suggest speed. In the bottom-right area, place a rounded white badge/card with a thin border containing two lines of text: a large bold headline reading "Up to €600" in a dark green, and a smaller gray subtext reading "for a delayed or cancelled flight." Overall mood: optimistic and clean, not somber — this pairs with ad copy about travelers being owed compensation. Keep the composition uncluttered, no extra icons or text elsewhere in the scene.

The image shows an airplane flying in the sky with the words "Up to £600 for a delayed or cancelled flight" written on the right side. The sky is filled with white, fluffy clouds, creating a peaceful atmosphere.
