Should the revised timetable prove incongruent with your plans, you can adjust your booking to an alternative flight within 14 days before or after the initially slated travel date. Notably, Southwest Airlines stands apart from its counterparts, as the extent of the flight alteration holds no sway over your eligibility for changes. There is no strict timeframe dictating the urgency of flight modifications, allowing you the freedom to initiate adjustments at your convenience.
