I had a pleasant experience with the cabin staff, who were attentive, friendly, and accommodating throughout the flight. Their professionalism made the journey more comfortable. The food and beverage were well-presented, and delicious, perfectly meeting my expectations. I appreciated that the airline accommodated dietary preferences (Seafood Meal), which enhanced my overall experience. I am writing this feedback on behalf of my friends and family who traveled in the economy class. We strongly believe that there is a splendid opportunity to further enrich the economy class experience by introducing a new feature for purchase, drawing inspiration from your existing product, 'Garuda Priority Service.' 1. Enhanced Meal Options Introduce a premium meal selection for purchase in the economy class. This would allow economy class passengers to relish business class meals. Providing the option to savor premium meals would undoubtedly elevate the travel experience for passengers. 2. Upgraded Amenity Kits Offer economy class passengers the opportunity to purchase enhanced amenity kits, inclusive of noise-canceling headphones and other amenities akin to those provided in the business class. The provision of these upgraded amenity kits would significantly enhance the in-flight comfort and overall experience for economy class travelers. 3. Displaying the menu on the in-flight entertainment screen would be helpful. 4. Implementing a system similar to Tapendium, where passengers can order snacks, beverages, and other items directly from the in-flight entertainment screen, would further enhance the passenger experience.
