Detroit is one of Spirit's flight attendant bases, along with Atlantic City, Dallas-Ft. Worth, Ft. Lauderdale, Las Vegas and Chicago.

"We're adding 15 new aircraft to our fleet this year and we need more great flight attendants to fly with us," said Laurie Villa, Spirit's vice president and chief human resources officer in a written statement.

The airline is known for its low fares and for its add-on fees, including carry-on luggage charges.
