History
If two or more passengers with the same booking number check-in simultaneously, the number of pieces allowed following the baggage allowance for each passenger may be combined. However, the weight per each piece cannot exceed the allowance granted per person.
For group tickets under the same PNR, the checked baggage weight may be combined. For all other bookings, passengers may not exceed the individual baggage allowance, and combining the number of baggage pieces is not permitted.
