With options for cabin and checked luggage, Scoot Airlines Baggage Allowance Policy Each of the options for which passengers may opt from has a varying weight limit for luggage. Though extra weight is available to purchase, the average weight allowance for carry-on is 7 kg. Twenty kilograms is the starting weight allowance for checked baggage, though this may be increased. Furthermore, Scoot allows the passenger to easily add more bags or change his or her baggage needs either before or after booking a reservation.
