To get the best deal on Spirit Airlines, strategic planning is key. First, flexibility reigns. Keep your travel dates open, aiming for midweek departures and returns for lower fares. Sign up for your Fare Club membership to get exclusive deals and discounts. Always book in advance, ideally several weeks in advance, as last-minute reservations are often expensive. Monitor your website regularly and set up price alerts to detect sudden drops. Consider opting out of add-ons like seat selection and luggage to further reduce costs. Remember, patience and perseverance are virtues when searching for the best Spirit Airlines deal.
