I recently flew to Singapore on flight 21 April 28, 2024. From the time I was greeted at the aircraft door your cabin crew was warm welcoming, smiling and dressed sharped in their uniforms. I've flown around the world and this was my first time on singapore airline. Jason was very attentive to all of my needs. Kelly did made sure my food was correct and it was served at perfect temperature. Mohan check made sure i stayed hydrated they did a beautiful dinner service and lunch service. Everytime I went to the bathroom Ploy had my favorite drink ready. Even though I was in premium economy they gave us first class treatment. I truly enjoyed everything from start to finish on my flight. Even though this is the longest flight in the world I was thankful for the comfort your crew provided me in this journey. Having this amazing crew will surely bring me back on your airline for my vacation travel to Asia. Please give them a special thanks from me. These are memories I will cherish.
