Spirit Airlines’ terminal at George Bush Intercontinental Airport (IAH) is located in Terminal A, which serves domestic flights. Spirit Airlines IAH Terminal has a clean, modern appearance with basic airport services. It has basic amenities like as seating places, food and beverage selections, and restrooms, but as a low-cost carrier, Spirit Airlines provides a more streamlined experience. The terminal can feel busier at peak travel times, so passengers are advised to arrive early to allow for security checks and boarding. Spirit passengers, like those of other low-cost carriers, should expect minimal frills in the terminal, with an emphasis on efficiency rather than elegance. The signage is clear, directing travelers through check-in, baggage drop, and security.
