Whether an airport trolley (luggage cart) is free depends entirely on the specific airport's management and the country's local customs. In the United Kingdom, Europe, and Asia, trolleys are almost universally free of charge in the arrivals hall, though some European airports use a "coin-return" system (like a supermarket cart) where you insert a €1 or £1 coin that is returned when you dock the trolley. In contrast, major United States airports (like JFK, LAX, or MIA) usually charge a fee, typically ranging from $6.00 to $8.00 per trolley, payable by credit card at automated Smarte Carte dispensers. This is often a shock to international travelers. However, even in the U.S., trolleys are usually free once you pass through Customs in the international arrivals area. Some premium airports in the Middle East, like Doha Hamad or Dubai International, provide complimentary trolleys throughout the entire terminal as part of their 5-star service standards. If you are flying in 2026, it is wise to check the airport's website beforehand; if they charge, consider using a "spinner" suitcase that reduces the need for a cart entirely.
