Narrative: ZZZ-ZZZ1 Fumes Odor in Cockpit [while] Airborne. Flight crew had previously flown leg (flight) ZZZ2-ZZZ on time in same aircraft. XA40 flight pushed from ZZZ on time.XB00 Airborne at cruise; Captain and First Officer smell light increasing volume of old sock odor and fumes smell. First Officer said it was giving him a headache. Captain said he could; '...taste it in the air.' Crew completed 'Elimination of Foul Odors in Flight Deck' procedure. O2 masks were on.XB05 Captain contacted Flight Attendant A (name) to ask if she smelled anything in cabin. She said 'no' so we; in step with QRH procedure; determined that fumes were coming from Pack 1; and shut off pack 1. Cabin pressurization remained stable. Per QRH procedure; after a measured 5 minutes of time; we assessed that fumes had dissipated and per QRH; 'No further action required.' and continued to destination ZZZ1.XB10p Notified AS Dispatch and Maintenance via ACARS. Dispatch replied acknowledgment and stated had notified Duty Manager.XB25p Captain contacted Flight Attendant A again via intercom to confirm no fumes in cabin. She replied that she could smell a light odor fumes only near cockpit door.No additional fumes noticed by cockpit crew until XC40. Note: Flight attendant communication and coordination during and after flight was very excellent.XC40 At top of descent; in managed descent mode upon thrust reduction; fumes odor returned to cockpit. Captain and First Officer re-donned masks did not [advise ATC]; were given increased speed in descent down arrival. Pack 1 was off entire remainder of flight.XD01 First Officer uneventfully landed aircraft on Runway XXR in ZZZ1. After landing; started APU; however; as APU air use increased odor/fumes; APU air was taken off.XD07 Flight entered gate (number) and deplaned. Contacted Maintenance via radio who requested flight crew stay with aircraft as to describe event to maintenance tech. Captain experienced slight burning eyes and First Officer slight nausea.XD20 Captain called [Duty Manager] who instructed us to remain in jetway for ZZZ1 CFR EMT to arrive for initial medical evaluation.XD25 AS Maintenance Tech arrived (name); who stated upon entering cabin that he could smell oil fumes.XD52 ZZZ1 CFR EMT arrive and do quick health assessment. Gives crew reference to hospital for blood chem/CO2 test.XF08 Captain recontacted [Duty Manager] and notified of we were enroute to hospital for blood tests s were flight attendants.XF35a Captain contacted [Crew Scheduling]; spoke to (name) who we notified that we were on way to hospital. He asked for us to contact [Crew Scheduling] after getting back to assigned hotel to adjust end of duty time.XF45 Hospital Emergency Room: paperwork; blood work and waited for results. Hospital ER Doctor said that only my First Officer's blood showed elevated; above standard levels of CO2; but under an amount which they consider dangerous. She provided paperwork that stated all crew were clear to return to work.XH15 Left hospital for assigned crew hotel.XH30 Arrived into hotel. Captain contacted [Crew Scheduling]; as per previous instructions; notified of flight crews arrival to hotel. [Crew Scheduling] rep (name) stated that her co-worker (name) was incorrect and our duty day had in fact ended after our landing in ZZZ1 earlier and time spent in hospital emergency room due to fume event was irrelevant. Furthermore; we were expected to show on time at XA50; getting less than the required 10 hours of rest. And we hadn't even made it to our rooms yet. We replied that as we were both exhausted from the event; EMT; blood draw; and long hospital process; that even if were able to immediately fall asleep upon getting to room; we weren't probably going to be in any condition on reduced rest to do tomorrow's (now today's) next flight. (Name) said that we could call in sick. Captain and I were shocked and disappointed in this altered [Crew Scheduling] interpretation. We replied that we would try to get enough rest.XI15 Approximately; I got to sleep.XO05 I awoke to use restroom; immediately recognized exhaustion and inability to get enough sleep in reduced time. I called Crew Scheduling and called in 'Fatigue.'Cockpit crew experienced various volumes of fumes/sock odor causing physiological impact and required crew to be screened by Airport Fire Department EMT and then go to local emergency hospital for chemical blood analysis; which showed minimal but measurable levels of CO2 crew blood.[Crew Scheduling]'s questionable alteration and re-definition of flight crew duty day not taking into account the long and arduous safety and health procedures post flight including EMT analysis and late night into morning hospital emergency visits with blood draw AND further insistence that crew continue onto next flight of pairing with real reduced rest is dubious; unsafe and detrimental to the on time and safe flight operations at company. A veteran of six previous airlines; I have never seen a flight operation which would have a flight crew continue flying who had recently experienced an physiological impact event such as fumes and on top of that; a reduced real rest period. I highly recommend that (name); in the interest of safety and operational integrity; changes their procedure so that any crew who has experienced any impact to their health in such an event; be automatically removed from flight status for at least a day.


Second narrative: Cabin Air Quality event. Dirty socks odor in cabin mostly around Row 30; also much stronger in flight deck and forward galley area. All crew members reported illness due to fumes. We all were examined by paramedics; and went to emergency room at local hospital.


Synopsis: A320 flight crew reported a fume event of varying intensity during entire flight. Entire flight crew received medical evaluation at local hospital for physiological symptoms.
