Yes, in 2026, the United States remains one of the few major countries where almost all international arriving passengers must collect and recheck their baggage at their first point of entry. Even if your luggage is "checked through" to a final destination like London or Mexico City, U.S. Customs and Border Protection (CBP) requires you to physically claim your bags after clearing immigration to walk them through the customs inspection area. Once you clear customs, there is typically a dedicated "Baggage Drop" belt immediately outside the secure area where you can hand your bags back to the airline without having to go back to the main check-in desk. The only major exception to this rule is for passengers arriving from "Preclearance" airports (mostly in Canada, Ireland, and the Caribbean), where you clear U.S. customs at your departure city and arrive in the U.S. as a domestic passenger.
