Finally, the low-fare carrier Spirit Airlines has a special deal offering 30% off airfare — but flights must be booked by Wednesday, May 31 — that is, today. Travelers should enter the code 30PCT on the airline site’s promotional code box, and note that the 30% discount only applies to the airfare portion of your total flight price — in other words, it doesn’t apply to taxes and mandatory fees.
