Excess baggage is extra weight or an extra piece beyond the fare allowance. It is sold by the airline (during booking as an extra, or at the airport). Sharifi Neya can request it before ticketing; it is not automatic and the price is the airline’s. Prepaid extras are usually cheaper than airport counters, but not always available on every fare. Can I add excess after I have a PNR? Sometimes, as an airline SSR. Ask the office with your PNR. Do not arrive at KBL counting on a walk-up extra without checking.
