If you're wondering about Spirit Airlines standby  the airline generally does not have a traditional standby process like other carriers. Spirit Airlines operates on a low-cost model, and they don't offer free standby for passengers who miss their flight or want to switch to an earlier one. However, you can book a new flight for a later time, often for a fee. If you want flexibility, you may consider adding Flight Flex to your booking, which provides some options for rebooking flights with reduced fees. Always check with Spirit for the latest policies, as they can change.
