DENVER — Even as systems came back online after a global computer outage because of a faulty software upgrade Friday, the impacts were still being felt at Denver International Airport. Passengers stood in long lines at customer service desks for several major airports Friday afternoon, working to rebook flights that had been canceled or delayed. Steve On Your Side confirmed with the U.

S. Department of Transportation that delays and cancellations caused by the outage are considered “controllable,” which opens up consumers to a range of accommodations offered by airlines in customer service plans filed with the federal government. If your flight was canceled, you can get a refund if you don’t rebook It doesn’t matter whether a flight cancellation was controllable or not, if an airline cancels a flight , USDOT policy says customers are entitled to a full refund if they choose not to rebook.

“So, if you booked a weekend trip and now your flight's muddy, pushed out into Saturday, and you're wondering, OK, it doesn't really feel like it's worth even going anymore – you can cancel,” said Sean Cudahy , an aviation reporter with the website The Points Guy . “If you accept the airline's offer to rebook at a later date, you wouldn't be eligible," Cudahy said. "But that's certainly something to have in mind.

” Because the outage is “controllable," airlines' federal customer service plans activate Cudahy said passengers who face severe delays should consult the DOT’.
