The airline has stranded passengers as it battles bad weather and worker shortages.
Thousands of Spirit Airlines passengers are still facing canceled flights on Thursday as the airline's operational meltdown stretches into a third day.
As of Thursday, Spirit canceled 360 flights, or 45% of its daily operations.
So far this week, Spirit has had to cancel around half of its flights each day: 42% of its Monday flights, 61% of its Tuesday flights and 60% on Wednesday.
"What's this been like for you?" ABC News' Correspondent Victor Oquendo asked a traveler who has been trying to get to Washington, D.C., from Miami.
"Nothing to eat, nothing to drink, nothing," Natasha Baptiste responded.
Other Spirit customers told ABC News that they were stranded and forced to spend the night at Spirit bases such as Fort-Lauderdale Hollywood International Airport in Florida.
The airline initially said cancelations would slow down by Tuesday, but a spokesperson explained that the cancelations were the result of a "perfect storm," blaming weather, staffing shortages and crews reaching the hour limits in which they are legally able to fly.
In its latest statement issued on Wednesday, Spirit vowed that the cancelations will finally start dropping on Thursday.
"We've dealt with overlapping operational challenges including weather, system outages and staffing shortages that caused widespread irregularities in our operation and impacted crew scheduling," Spirit said in a statement. "These issues were exacerbated by the fact that we are in peak summer travel season with very high industry load factors and more limited options for Guest re-accommodations."
After being hit with an IT issue Tuesday that affected crew scheduling, the airline said they have "implemented a more thorough reboot of the network" which allows them to get crews where they need to be to restore normal operations.
The airline will now provide double pay to flight attendants who pick up extra shifts.
The low-cost carrier said that they've taken an "in-depth" look at the challenges they are currently facing and have "identified opportunities for improvement."
"We continue to work around the clock to get our Guests where they need to be," Spirit insisted.
Spirit recommends customers affected by the cancelations use its online chat feature for assistance.
The cancelations come as air travel continues to break pandemic records.
Transportation Security Administration officers screened more than 2.2 million people at U.S. airports nationwide Sunday -- the highest checkpoint volume since the start of the pandemic.
