The baggage allowance for your flight from London Gatwick Airport will depend on your airline and ticket type. Most airlines allow passengers to bring one piece of hand luggage and one checked bag, although the weight and size limits may vary. Some airlines may charge extra fees for excess or overweight baggage, so it's important to check with your airline before you fly. You can find information about baggage allowances and fees on your airline's website or by contacting their customer service.
