The flight was unfortunately delayed. Boarding was chaotic and disorganized. Throughout the entire journey, I felt uncomfortably cold despite wearing a hoodie and using my blanket. The seats were non-reclining, and the limited legroom and narrow space on both sides made it difficult to access my belongings. Overall, the flight was an uncomfortable experience. Onboard food was overpriced, and I was disappointed with the simple egg sandwich I received.
