Most would agree that hotel guests do not want to wake up to the smell of jet fuel and car exhaust. While indoor air quality may not have been a concern when the iconic TWA Flight Center opened in 1962 at New York’s John F. Kennedy International Airport (then called Idlewild Airport), nearly 60 years later it is. When the landmark building reopened as the TWA Hotel this past spring, it became JFK’s first on-airport hotel. Located directly across from JetBlue’s Terminal 5, the TWA Hotel is accessible via car, AirTrain, or directly from the arrivals level of the terminal. Given the hotel’s proximity to transportation, it is estimated that countless guests will be passing through this hotel and a key component to serving them is to maintain healthy, comfortable indoor air quality.
