6. London Heathrow

Sadly, this London airport has also made Travel + Leisure’s ugliest airports list. In fact, the airport is described as “four shopping malls that have been smashed together.” Terminal 3 is the worst, distinguished by a system in which passengers are corralled into a central seating area and not permitted to pass through security to their gates until departure time.
