Video above: Flight delays not done as holiday travelers try to make their way home

Air travelers in the U.S. hoping for clear skies on Tuesday following a disastrous week of weather-related flight cancellations and delays will have to extend their patience a few more days -- particularly if they're flying with Southwest Airlines.

More than 2,750 flights within, into or out of the U.S. have already been canceled for Tuesday as of 2:45 a.m. ET, according to flight tracking website FlightAware.

Of those canceled flights, 2,480 are operated by Southwest.

Airports most affected by the Tuesday cancellations are Denver International, followed by Chicago Midway International, Baltimore/Washington International, Nashville International, Dallas Love Field and Harry Reid International Airport in Las Vegas.

Tuesday's cancellations follow a full day of post-Christmas travel chaos, with 3,989 flights canceled on Monday -- 2,909 of those being Southwest flights.

Southwest warns that such cancellations and delays are expected to continue for several more days, with representatives saying the Dallas-based airline is planning to dial back its flight schedule in order to get operations on track.

Southwest Airlines CEO Bob Jordan told the Wall Street Journal the company plans to operate just over a third of its schedule in upcoming days to give itself the ability for crews to get into the right positions.

According to WSJ.com, Jordan added that reduced schedule could be extended.

"We had a tough day today. In all likelihood we'll have another tough day tomorrow as we work our way out of this," Jordan said in an interview Monday evening with WSJ.com.

"This is the largest scale event that I've ever seen."

What can stranded passengers do?

CNN's Carlos Suarez spoke with frustrated passengers in line at the Southwest ticket counter at Hartsfield-Jackson Atlanta International Airport on Monday afternoon.

He reported that about 150 customers were waiting in a long line at one point to rebook, with the line snaking around the back of the ticket counter.

Calls made Monday afternoon by CNN to Southwest's customer service did not go through, so customers couldn't even get in the queue to speak to a representative. Southwest told CNN it is "fully staffed to answer calls."

The airline also says, "those whose flights have been canceled may request a full refund or receive a flight credit, which does not expire."

If you've been left in the lurch and your efforts to reach a customer service agent are going nowhere, the founder of Scott's Cheap Flights suggests trying an international number.

"The main hotline for U.S. airlines will be clogged with other passengers getting rebooked. To get through to an agent quickly, call any one of the airline's dozens of international offices," Scott Keyes said.

"Agents can handle your reservation just like US-based ones can, but there's virtually no wait to get through."

Southwest spokesperson: "Take care of yourself...keep your receipts"

A spokesperson for Southwest Airlines (SWA) said the recent winter storm is to blame for the cascade of thousands of flight cancellations Monday and advanced cancellations Tuesday.

"As the storm continued to sweep across the country it continued to impact many of our larger stations and so the cancellations just compiled one after another to 100 to 150 to 1,000," Jay McVay said in a press conference at Houston's William P. Hobby Airport on Monday night.

"With those cancellations and as a result, we end up with flight crews and airplanes that are out of place and not in the cities that they need to be in to continue to run our operations."

McVay said that the company's first priority right now is safety. "We want to make sure that we operate these flights safely and that we have the flight crews that have legal and sufficient time to operate these flights," he stated.

"We will do everything that we need to do to right the challenges that we've had right now," he said, including "hotels, ride assistance, vans ... rental cars to try and make sure these folks get home as quickly as possible."

He promised that all customers, even those who had already left the airport or made alternate arrangements on their own, would also be taken care of.

"If you've already left, take care of yourself, do what you need to do for your family, keep your receipts," McVay relayed. "We will make sure they are taken care of, that is not a question."

An announcement made in the terminal prior to the news conference apologized to customers and said the next available SWA seats are on Saturday, Dec. 31 and later. The agent said Southwest would be providing buses to area hotels and assured that "we will have sufficient rooms for all customers who are affected by this disruption."

US government 'concerned' by cancellations

The United State Department of Transportation (USDOT) issued a statement on Monday's massive flight cancellations by Southwest Airlines, saying the agency is "concerned."

"USDOT is concerned by Southwest's unacceptable rate of cancellations and delays and reports of lack of prompt customer service. The Department will examine whether cancellations were controllable and if Southwest is complying with its customer service plan," the agency tweeted.

Meanwhile, in a call with CNN on Monday, the president of the Southwest Airlines Pilots Association, Capt. Casey Murray, said the problems Southwest is experiencing have been brewing for a long time.

"We've been having these issues for the past 20 months," he said. "We've seen these sorts of meltdowns occur on a much more regular basis and it really just has to do with outdated processes and outdated IT."

When asked about the airline's processes, he said they haven't changed since the 1990s. "It's phones, it's computers, it's processing power, it's the programs used to connect us to airplanes -- that's where the problem lies, and it's systemic throughout the whole airline."

"This ultimately is a leadership problem," Murray stated. "Until we have some true leadership that is going to make some changes and really bring this airline into the 21st century we're going to continue to see this, and our customers and our employees are going to continue to suffer."

In other developments

A rough holiday week

A winter storm that swept across the US was ill-timed for travelers who had started pushing Christmas week flying numbers back toward pre-pandemic levels.

On Christmas Day, 3,178 flights were canceled and 6,870 were delayed, according to FlightAware.

On Christmas Eve, there were a total of 3,487 flights canceled, according to FlightAware.

Friday was the worst day of this streak, with 5,934 cancellations, while Thursday saw almost 2,700 cancellations.

Severe winter weather that has spread across the United States this week could cause delays with your packages. 

FedEx's Memphis, Tennessee headquarters is under an ice storm warning as the company tries to avoid any disruptions in deliveries.

The company says it's keeping an eye on the weather, but the safety of employees comes first.

FedEx released a service statement on its website which said, "FedEx Express experienced substantial disruptions at the Memphis and Indianapolis hubs last night due to freezing rain in the Memphis area and snow in the Indianapolis area. The storm has created potentially hazardous operating conditions and the safety of our team members remains our number one priority. Potential delays are possible for package deliveries across the U.S. with a delivery commitment of February 3, 2022. Contingency plans are in place and we are prepared to provide the best possible service as conditions allow. Operational impacts to other FedEx operating companies may vary due to local weather conditions."

A major winter storm has left more than 200,000 homes and businesses without power across the U.S. The multiday storm dumped more than a foot of snow in parts of the Midwest and triggered weather warnings from Texas to the Northeast. Power companies have struggled to keep pace with freezing rain and snow that weighed down tree limbs and encrusted power lines.

Travelers also are dealing with thousands of canceled flights around the U.S. The storm's path stretched further from the central U.S. on Thursday into more of the South and Northeast. Forecasters say more heavy snow is expected, while heavy ice buildup was likely from Texas to Pennsylvania.
