There are many reasons that contribute to the renowned inflight of SQ. They are the stringent interview processes,the experienced interviewers,the rigorous training (4 months compared to 1 to 2 months for most airlines),the management support,the quality of the trainees recruited etc etc...
In my most humble opinion,it is the strong SIA cabin crew culture that had been passed down from people like Cyril Teo, Peter Chong,Willy Goh, Edward Lim Habiba,Fatima,Dolly Tan,Vivian Khoo,Betty Leong,Bee Hwa etc from the first few batches of stewards and stewardesses that has been ingrained in the hearts and minds of the cabin crew.This culture has been the strongest influence on the high standard of our inflight service today.
We had been fortunate to inherit the culture of pride in our service towards our passengers. SQ cabin crew,in their hearts know that passenger satisfaction is their satisfaction too. So everything that the crew does will always be done with diligence and pride.
The respect bestowed on the senior crew by their juniors is another influence on the inflight service standard. You hardly hear of junior crew having their meals on the flight,no matter how hungry they may be,before their senior. Unless the senior crew do not want to eat first,then with permission, the junior will have their meals.This applies to drinks,greetings etc.
However of late,the juniors are getting less respectful of their seniors and the false and much misunderstood signals that the management sends to them to even report the seniors if they had done wrong,make them much bolder.
Click here if you don't believe me and you would read of the complains they have of their juniors.However,let's hope those type of junior crew are in the minority.
Let us not forget those pioneers whose names I have mentioned above and many others whom I do not have the time to mention. They made us all proud of them for their wonderful contribution which today has made us excellent service providers.
