Preclearance! Which Other Airports Should Have It?

Preclearance programs let travelers clear US customs and immigration at the departure airport, so they arrive in the US as domestic passengers. The system is currently limited to just over a dozen airports worldwide, including a few Canadian airports and Dublin, Ireland, with others in the Caribbean, Europe, and the Middle East. Expanding the roster could boost connectivity to the United States and ease post-landing experiences for international travelers who would bypass lengthy arrivals procedures. The author argues London Heathrow Airport (LHR) would be a strong candidate due to its broad links to US hubs and its role in transatlantic joint ventures, which can offer more reliable connections.

London’s status as a major transfer point would streamline onward connections for travelers entering the US and for passengers already moving within the US network. Heathrow hosts several airlines operating between London and the US and participates in transatlantic joint ventures that could bolster scheduling and reliability across peak travel periods. By extending Preclearance to additional gateways, the network could improve connectivity not only to the US but within the broader international footprint, potentially boosting tourism and business travel. The article invites readers to share which airports they believe should join the Preclearance program, highlighting the debate over efficiency, security, and policy.
