O'Hare International Airport and JFK are among the most stressful airports in North America according to a survey carried out among business travellers and published this week.

U.S. Thanksgiving is around the corner and travelers are getting ready for one of the busiest travel periods of the year. A new survey published this week by Concur reveals the most stressful airports across the country.

According to the survey, the most stressful airport in the country is Chicago O'Hare, closely followed by New York's JFK International airport.

Over 56% of the respondents surveyed complained about the long distances between gates and terminals at Chicago O'Hare. For 49%, JFK presents some of the longest lines.

Among the leading stress factors at airports, respondents cited confusing airport signage (28%), poor service from airport staff (28%), not enough and crowded bathrooms (19%), poor wifFi coverage (19%) and insufficient amount of electrical outlets (18%).

The survey, published this week, was carried out online in August among 1,500 respondents in the US and Canada who travel regularly for business.

A survey carried out by Daily Beast last year featured the Chicago hub as the nation's worst airport among 30 airports across the country. The report said O'Hare had the worst on-time performance, with only 67.6% of arrivals and 70.3% of departures having been on time. O'Hare was followed by New York's Newark and JFK.
