According to Salt Lake International Airport, seven outbound flights to SFO Airport were cancelled. It was unclear how many inbound flights were delayed or cancelled as of Saturday afternoon.
Passengers at Salt Lake International said they were frustrated by the confusion. Many received conflicting reports from airlines as to the status of their flights.
Hilary Stevenson from San Francisco was headed home with her family after vacationing at Yellowstone National Park. She was unaware her flight was delayed until she arrived at SLC International Airport.
"We decided not to check in our bags because we realized we might not be going anywhere," she said.
The cause of the flight cancellations was due to an Asiana Airlines flight that made a crash landing on the runway of the San Francisco International Airport, according to a federal aviation official. Dozens of people were injured and several are listed in critical condition.
Federal Aviation Administration spokesman Lynn Lunsford says the Boeing 777 crashed at San Francisco Airport while landing on Saturday. The flight was carrying 290 passengers and one infant.
Asiana flight 214, a Boeing 777, was traveling from Seoul, South Korea, to San Francisco.
