The six to seven-hour hop across the pond has been one of the most popular International routes from the US. As the journey has primarily been operated by widebody aircraft, narrowbody planes have populated it more recently and are expected to continue to do so indefinitely, thanks to newer planes. In fact, long-haul narrowbody aircraft have also allowed airlines to begin service to new markets that otherwise could not be served. Nonetheless, widebody aircraft continue to dominate flights between the US and the UK.
