The last four legs, SJC-DFW-BWI-DFW-SJC, the air quality was very bad. Is AA saving by recirculating differently. In the front of the plane the air seemed more stale, but when I walked to the back, the smells were very bad, as they were in the rest rooms.

Has anyone else noticed?

Does this have to do with the amount of fresh air and that the more fresh air the higher the cost?

All the flights were on time or early; that's a plus.
