What is a common feature of CTA buses that enhances passenger comfort?

Climate control with heating and air conditioning is a common feature of CTA buses that significantly enhances passenger comfort. This system ensures that riders are kept at a comfortable temperature regardless of the weather conditions outside. In winter months, the heating keeps the interior warm, while in the summer, air conditioning provides a cool environment, making the journey more pleasant for commuters.

While other options may seem appealing, they are not standard features across the entire fleet. For instance, reclining seats may not be practical for city buses, overhead storage compartments are typically found in coach buses rather than transit buses, and while free WiFi access might be offered on some buses, it is not universally available on all CTA routes. Therefore, climate control is the essential feature that consistently contributes to passenger comfort across the CTA bus network.
