In celebration of the airline's 85% on-time arrival rate in March, Spirit is running a flash sale offering 85% off flights until midnight on May 2.
Get to the budget airline's sale page and use the code "85PCT" to dig up deals flying out of your local airport. You can find round-trip flights for as little as $50. However, to take advantage of the deal you must book by midnight for trips between May 9 and June 13 or between September 5 and October 31.
The discount isn't available on every flight, but a ton of flights out of many cities are eligible for the deal. There are only a handful of routes excluded from the sale.
