Spirit Airlines will shut down operations immediately following a failed White House bailout plan and "extensive and comprehensive efforts to restructure the business," the airline said Saturday.

A Spirit Airlines plane takes off at Los Angeles International Airport.

Airport kiosks for Spirit, which entered bankruptcy in August for the second time in a year, on Saturday displayed a goodbye message and employees were alerted they're being let go.

The airline's website tells customers not to go to the airport, and anyone with a ticket for a now-nonexistent flight will be issued refunds.

Several other airlines, including United, Delta, Southwest and American, have announced “rescue fare” plans for Spirit customers with booked flights that will no longer take place.
