Design a Facebook post graphic (1200x628px) for an air ticket business aimed at frequent travelers and families. Use a bold and rich color scheme with a gradient background transitioning from deep blue to vibrant orange to create an eye-catching effect. Feature an image of a happy family boarding a plane on the left side, depicted in a joyful manner to showcase their excitement for travel. On the right, include the text 'Book Your Dream Vacation Today!' in large, modern sans-serif font (e.g., Open Sans or Lato), ensuring it is bold and easily readable with a contrasting color (white or light yellow). Add a prominent CTA button 'Call Now' in white text on a bright red background at the bottom-right corner, ensuring it stands out. Ensure the overall layout is balanced with ample negative space for clarity and visual appeal. Image tag AirTicket_Book_Your_Vacation_Post.
