Hi everyone, if you're a budget traveler like myself, Spirit Airlines ORD Terminal is an acceptable choice. You won't have luxury, but it suffices. I went last week and had a swift check-in, although I would advise to use the mobile app to expedite things. The terminal was tidy, albeit lacking in nearby food options, so eat beforehand. Employees were accommodating when I inquired about my gate. Flight was 20 minutes delayed, but not much. For the price you pay, it's reasonable. Just bring minimal baggage, be prepared for a minimalist experience, and you'll be just fine!
