Chaos as FAA grounds all Alaska Airlines flights due to problem with weight calculation system then lifts it an hour later

A one-hour ground stop on all Alaska Airlines flights has sparked travel chaos on Wednesday, delaying its entire fleet and spreading travel fears among passengers.

The U.S. Federal Aviation Administration issued a ground stop advisory for the airline at around 7:30 a.m. Pacific Time, writing: 'All Alaska mainline and subcarrier flights ground stopped.'

While the agency declined to provide a reason for the advisory, Alaska Airlines reported encountering a problem while updating software.

'This morning we experienced an issue while performing an upgrade to the system that calculates our weight and balance,' the airline said in a statement to DailyMail.com.

'A ground stop for all Alaska and Horizon flights was instituted at approximately 7:30am PT. The issue was mitigated and the ground stop for Alaska and Horizon flights expired at 8:30am PT.'

According to the airline, the issue stemmed from a software update to a weight- and balance-calculating system on the planes

The airline confirmed that it had begun to release flights, though residual delays were anticipated throughout the day. 

Flights for SkyWest, which provides regional service for Alaska Airlines, were excluded from the ground stop.

In a statement, the FAA said the carrier 'asked the FAA to pause the airline's mainline departures nationwide.'

Customers took to social media to rail against the unexpected service interruptions. 

'Crew on plane; you can deplane, just stay close by the gate. Gate crew: you can’t get off the plane. Back and forth,' one woman wrote on X, formerly Twitter.

'Everyone has walked talkies yet 0 communication between plane and gate. We reboard and pilot tells passenger “you can go get coffee."'

Another man tagged the airline, demanding they provide reason for the delays.

'I’ve been sitting in this airplane for 2 hours! Was supposed to be a 3 hours flight,' he wrote. '@SpiritAirlines sounds better right about now.'

A Texas woman claimed her flight had been sitting on the tarmac for nearly three hours, even after the advisory had been lifted

Another passenger reported that her flight had been sitting on the tarmac at a Texas airport for nearly three hours.

'Was supposed to leave at 8:30am (CDT) and we are still sitting on our plane at 11:06am,' she wrote.

It was not immediately clear how many flights were impacted. 

The airline urged travelers to check their flight status either online or through its app before heading to the airport. 

Alaska's fleet of 314 planes is comprised of 231 Boeing 737 aircrafts and 83 Embraer 175 aircrafts. 

Earlier this year, the airline was forced to cancel thousands of flights after a door plug on a 737 Max 9 blew off shortly after liftoff from Portland International Airport.

Following a thorough inspection, the crafts were cleared to resume flying. Boeing shelled out $160 million earlier this month to make up for losses the airline had suffered. 

Wednesday's grounding came as Senate committees held dual hearings investigating allegations of safety failures and substandard production quality at the aircraft manufacturer.

When asked if the software issues had any relation to issues with Boeing aircrafts, a spokesperson told DailyMail.com the matters were 'completely unrelated.'
