These are the worst airports and flight routes for turbulence in North America
They say knowledge is power — and with this in mind, we are revealing the airports and flight routes in North America that are the worst for turbulence.
Armed with this knowledge, nervous flyers will at least know to expect a few bumps in these spots.
The lists come from website turbli.com, which monitors and predicts turbulence using the same sources pilots and airlines use to plan their flights – the National Oceanic and Atmospheric Administration (NOAA) and the MetOffice.
The most turbulent airport for approaches and descents — take-offs and landings are affected by crosswinds, not turbulence — is Denver, Colorado, followed by Bozeman Yellowstone International Airport.
They both have average annual EDR scores ("eddy dissipation rates") of 17, a unit that describes how fast turbulence disappears.
The website describes EDR values of 0 to 20 as "light — smooth flight conditions"; 20 to 40 as "moderate", leading to "difficulty with walking and food services"; 40 to 60 as "strong", with passengers straining against seat belts; 60 to 80 as "severe", with "violent and sudden changes in altitude; and 80 to 100 as "extreme", meaning the "aircraft is practically impossible to control".
Salt Lake City, Jackson Hole Airport and Las Vegas also make the top 10, with Albuquerque to Denver ranked as the route with the highest average turbulence.
Las Vegas to Reno and Las Vegas to Salt Lake City also make the top 10 most turbulent route table.
Turbulence is caused by warm air rising through cooler air; mountains or manmade structures disrupting air flow, and pockets of air moving in different directions.
It's completely normal and modern aircraft are designed to withstand more turbulence than you'll ever experience on a flight.
According to data from America's Federal Aviation Administration (FAA), there have been only 184 serious turbulence injuries between 2009 and 2023, with 37 of those people passengers, the rest crew members.
Denver (17.29 EDR — eddy dissipation rate)
Bozeman (17)
Albuquerque (16.44)
Salt Lake City(16.43)
Jackson Hole Airport (16.14)
Las Vegas (15.74)
Vancouver (15.68)
Reno (15.67)
Seattle (15.49)
Boise (15.40)
Albuquerque — Denver (17.75 EDR)
Denver — Jackson (17.45)
Jackson — Salt Lake City (17.41)
Denver — Salt Lake City (16.94)
Bozeman — Denver (16.68)
Ontario — San Diego (16.43)
Boise — Salt Lake City (16.30)
Bozeman — Salt Lake City (16.25)
Las Vegas — Reno (16.06)
Las Vegas — Salt Lake City (15.87)

FAA slashes flights in, out of Newark Airport through end of 2025
Hourly flights at beleaguered Newark Liberty International Airport will remain drastically reduced through the end of the year as construction and staffing shortages continue plaguing the busy travel hub, the Federal Aviation Administration confirmed Friday. Just 28 arriving and departing flights will be permitted each hour on weekends from Sept. 1 through Dec. 31, as critical airport construction presses on. The rest of the time, there will only be 34 arrivals and departures through Oct. 25, the FAA said in a statement. 'The confirmed reduced rates will maintain safety while alleviating excessive flight delays at the airport due to staffing and equipment challenges, the agency said. 'The early completion of runway construction at the airport that added to the delays will also contribute to a more efficient operation.' Runway 4L-22R, which shut down on April 15 after the FAA deemed it unsafe and ordered a $121 million repair project, reopened Monday, 13 days ahead of schedule. The closure had left just two open runways. The FAA last month cut Newark's flight capacity to 56, a fraction of the 80-plus that used to fly in and out, during the project that had left just two open runways. The New Jersey airport has been embroiled in disaster after disaster this year, ranging from air traffic controller shortages to inexplicable technology glitches on top of the endless work. The mass chaos has left thousands of travelers stranded ever since the first tech disaster on April 28 saw a burnt-out copper wire spark a full-on blackout at the airport. Many pointed fingers at United Airlines, which makes up 75% of all Newark's flight traffic, and accused it of overcrowding the airport — prompting the carrier's CEO to vow that travel at the embattled airfield would be the 'cheapest' they've ever been this summer. The FAA assured that it is taking action to improve matters at Newark, including updating antiquated technology and boosting telecommunication connections, according to the release.

New York to Paris in Under Four Hours? Inside the Effort to Build the Next Concorde
When the Concorde was grounded in 2003, done in by strained economics and a fiery crash on a Paris runway, it appeared to be the end of the line for supersonic travel. Nothing emerged to replace it. In fact, the speed of air travel moved in the opposite direction, with many routes getting slower in recent years as congestion and air-traffic control inefficiencies jammed up the skies. A former Amazon software engineer named Blake Scholl founded a company to change this. A decade ago, he launched Boom Supersonic, betting that his Denver-based startup could tap in to the allure of ultrafast travel—a desire that has never quite been extinguished despite the financial and practical challenges that ended the Concorde's nearly 30-year run. Scholl sees a world where round-trip trans-Atlantic business journeys happen in a single day.

This Groupon deal can gets you a Costco membership for as little as $15
People that shop at Costco love to talk about being in Costco. Part of that is because it's pretty great, and part of that is because its at least mildly exclusive.
