Flights delayed, canceled at Boise Airport following CrowdStrike outage. What to know

Nearly 30 flights in or out of Boise Airport were delayed Friday, while another nine were canceled, as overnight Microsoft outages caused multiple airlines to ground flights.

Over 33,000 planes worldwide were either delayed or canceled Friday because of the outage, caused when a technology glitch related to Microsoft’s cloud services occurred, according to NBC News. Delta, United and American Airlines are the three leading airlines impacted.

Here’s what to know about the outage and what to do if your flight is affected.

Why is there a Microsoft outage?

The technology glitch originated from cybersecurity company CloudStrike, which provides services and software to some of the largest companies in the world that run on Microsoft, NBC News reported.

The outage caused problems for not only airlines but also information displays, log-in systems, retailers, and even banks and broadcasting networks, according to the New York Times.

Microsoft posted on the social media platform X Friday morning that all Microsoft apps and services had recovered, but users are still reporting issues.

How is the Boise Airport affected?

As of 10:30 a.m. Friday, Boise Airport spokesperson Shawna Samuelson told the Idaho Statesman that five departing flights had been canceled and there were “quite a few delays.”

The flight-tracking website FlightAware showed 17 delays and nine cancellations for flights coming in and out of the Boise Airport. Samuelson said systems have returned online, reducing delays as planes get the clearance to take off.

“I can’t speak on behalf of the airlines, but I think for the most part, they have their systems rebooted, and it’s operating as expected,” Samuelson said. “Now it is just that they’re absorbing the impacts of what happened earlier this morning.”

What to do if your flight is impacted

Travelers impacted by the outage will have to work with their airline directly to solve any issues.

“Passengers should definitely always check directly with your airline for your flight status,” Samuelson said. “That’s where you’ll get the most up-to-date information. And they also need to work with their airlines if they are displaced by the impacts of this outage.”

Delta, United and American Airlines have all offered travel waivers for customers affected by the outage. The waiver allows customers to rebook their flights, and the rebooking fees and fair difference will be waived.

Each airline may offer different deals and dates you need to rebook by. You can check information about each airline’s waiver at the links below:
