Booking flights online is the process of reserving air travel tickets through internet-based platforms without visiting a physical ticket office or travel agency. This method emerged as a convenient solution to meet the growing demand for quick, accessible, and self-managed travel planning.

Whether you're traveling for business, vacation, or emergencies, online booking platforms allow users to compare prices, choose routes, select seats, and pay securely—all from a smartphone or computer. As global travel has expanded, online flight booking has become the preferred mode of reservation for millions.

Why Online Flight Booking Matters Today

Online flight booking has transformed the way people plan travel. Its importance is evident in several areas:

  • Time and cost efficiency: You can view dozens of airline options instantly without visiting counters or making calls.
