Spirit Airlines has ceased operations as of 3:00 a.m. today, leaving passengers across the country scrambling to make alternate travel arrangements.

The sudden shutdown follows days of widespread disruptions, with many travelers already experiencing cancellations and delays leading up to the closure.

In response, federal officials — including President Donald Trump and Transportation Secretary Sean Duffy — have been involved in coordinating efforts with major airlines to assist stranded passengers.

Several carriers, including United Airlines, Delta Air Lines, JetBlue, and Southwest Airlines, are offering discounted fares for former Spirit customers. In addition, American Airlines and Delta are providing reduced pricing on routes that previously had heavy Spirit traffic, with some reports indicating efforts to keep fares stable on those routes.

Frontier Airlines has announced a 50% discount for affected passengers, available through May 10.

Passengers who purchased tickets directly through Spirit are expected to be eligible for refunds through a reserve fund established by the airline. Those who booked through third-party agents will need to contact their agent to initiate the refund process.

The shutdown also comes after the Biden administration, led by President Joe Biden and Transportation Secretary Pete Buttigieg, previously moved to block a proposed merger between JetBlue and Spirit — a decision that some industry observers had warned could impact the airline’s long-term stability.

Travelers impacted by the shutdown are urged to act quickly in securing alternate flights, as availability is expected to tighten in the coming days.
