Narrative: In this report you will find my irregularity reports that I have documented concerning toxic air syndrome that I have experienced while on duty at [Company].[Company] Safety Department said that 'the Hepa-Filters on [Company]'s aircraft are changed out on a regular schedule based.'I also understand that these maintenance procedures are codified in [Company] Technical Operations approved FAA Maintenance Manuals. With that said;How can I verify this for transparency; for each aircraft that I am flying on?1. ZZZ-ZZZ1; Flight # XXXX Serious illness work environment safety concern. After two hours of flying on this aircraft I started experiencing chronic symptoms (Listlessness; Headaches; Fatigue;) are just some of the symptoms I was experiencing as well as C-Flight Attendant and the inbound B- Flight Attendant briefly told me of her illnesses she was experiencing as well. I noticed that when we were on the ground and the galley doors were open; the symptoms went away. This continued all day to the point that I thought I was going to have to call scheduling to be pulled. I believe that this aircraft should be examined for whatever made me and my colleagues work environment physically fatigue.2. ZZZ2-ZZZ3; Flight # XXXYThe crew experienced jet fumes from the aircraft on takeoff from ZZZ2. When we landed in ZZZ3; the A and B Flight Attendants brought it to my attention how severely heavy the fumes they experienced on takeoff. These fumes weren't as heavily present in the back of the aircraft as the A and B Flight Attendants were experiencing. These aircraft fumes side effects caused me to experience a slight headache and pain in my eyes.3. Flight # XXXZ; ZZZ4-ZZZ5After 45 minutes into this flight; I started feeling symptoms; headaches; eye pain; feeling if I was going to faint; and nauseous. No; I am not pregnant! I woke up that morning feeling perfectly fine. Like I said before; the symptoms didn't start until 45 minutes after my first departure. The odor didn't appear to be as prevalent to me as it were for the inbound crew. I'm sure that whatever product they use to disinfect the carpet for that aircraft probably contributed to my temporary illness. In between flights I would step off the aircraft to get fresh air; this helped alleviate the symptoms and when my shift was over and I was off the aircraft I noticed the symptoms disappeared; so I know for a fact that the aircraft cabin environment was causing my symptoms.




Synopsis: Flight Attendant reported three prior fume events resulting physiological issues.
