Spirit Airlines ORD Terminal provides a simple, low-cost travel experience and is based out of Terminal 3. With choices for online, kiosk, or counter check-in, the check-in procedure is simple. Basic facilities including restaurants and shops are available at the port, albeit they could seem constrained during busy times. The staff is generally friendly, and the zone-based boarding procedure is effective. Spirit is still a sensible option for reasonably priced travel, even though the seats close to the gates sometimes get packed.
