Moreover, the punctuality rate of Singapore Airlines is still very high.
You don't need to pick up your luggage when you transfer in Singapore. When you get off the plane, go directly to the boarding gate of the flight back to Beijing. I just don't have time to visit duty-free shops.
For passengers with short transfer time, SIA should have staff to guide you to the next boarding gate after disembarking. At least Cathay Pacific in Hong Kong has such an arrangement.
But you still don't have to be afraid, even 10 thousand is impossible In case you miss it, or the first flight is delayed, it's the airline's responsibility. They will arrange the next flight back to Beijing for you free of charge.
