Because of the piece system. Flights to North America and certain other countries in the world use this.
The sizes of the bags you are allowed to check in are probably normal size. However, you get to check in 2 at up to 32kg each.
The weight system means you can check in normal size bags at 20kg and you're only allowed one.
Now, how can a Singapore Airlines Megatop allow passengers from HKG
up to 64kg, but from SIN
only 20kg for Y.
The idea is stupid. The piece system should be introduced everywhere. My mother would appreciate it.
Anyone can fly, only the best Soar.
