Singapore Airlines is upping the luggage allowance on its and SilkAir flights to match those of Emirates.
Economy passengers have 30 kg, business class 40 kg, and first class/suite passengers 50 kg limit. Star Alliance Gold members will have additional 20 kg allowance.
Note that the piece concept applies to flights to/from United States and Brazil. You can access Singapore Airlines press release about this change here.
The increase in checked baggage limits is a welcome relief to those that do shopping on their trips. I always try to travel just with my carry-on, although not always possible.
Singapore Airlines must have felt the competitive pressure from Emirates and had to adjust the allowances to match those of EK.
