Southwest Airlines is telling travelers to plan ahead as they continue to deal with the fallout after a major technical glitch.
The airline urged passengers to arrive at least two hours early Monday.
The problem first surfaced Sunday with check-in system issues, forcing workers to check some customers in with handwritten tickets.
By Monday morning many passengers reported that they were no longer experiencing problems, including one man who tried to check in online Sunday.
“It’s much better now. I definitely feel a lot better that it’s back up and running and that I was able to check in on my phone,” he said.
Pictures flooded social media of long lines at airports across the country.
Southwest said about 450 flights were delayed and they expect more delays again today.
Southwest Airlines says it's fixed the technology problems that delayed hundreds of flights Sunday and that it expects a normal day of operations, The Associated Press reported.
There were about 450 delays out of 3,600 flights scheduled Sunday.
