Narrative: On takeoff; both the FA's (Flight Attendant's) and myself noticed a slight smell in the aft of the aircraft; but it dissipated; so we just thought it was the jet fuel or deicing fluid. We didn't notice any unusual smells during flight. On descent; the smell returned; a lot stronger. It could be smelled in the front of the Cabin; we did go up front and confer with one another to determine if we should call the pilots (it was below 10;000 ft.). We decided to notify them on landing; as the odor was the only concern. As we returned to our jumpseats; the odor got increasingly strong; a mostly a chemical smell (different from the normal jet fuel smell that is common on the Airbus on takeoff and landing). Both myself and the B Flight Attendant felt nauseated and the smell was irritating our throats. I was gagging and almost threw up; and the B Flight Attendant said her throat felt tight and she also felt nauseated. After we disarmed our doors; I went to the bathroom because I thought I was going to throw up. My head started throbbing and I felt very nauseated and throat felt tight. I called the Flight Deck to notify them of the incident. They didn't smell the same odor; but came back to assess; and then we all got off the aircraft so we could get some fresh air. We stood in the jetway; the B Flight Attendant and I kept feeling increasingly worse. My head felt foggy and I was very nauseated. The Captain suggested I use the pilot oxygen; as I was feeling pretty bad; (my eyes were closed but going back and forth uncontrollably). So I went into the Flight Deck and used the Pilot Oxygen. That did help a bit. After conferring as a crew and with the CSA's (Customer Service Agent); the CSA's called the paramedics. The A FA and the C FA made most attempts at the list of Air Quality contacts. Services wanted us to evacuate the jetway and get away from the aircraft; so we went into the terminal. As the paramedics evaluated us; we attempted on multiple phones to get in contact with MedAire. The A FA got a hold of someone first; and that person told the A FA that we each individually had to call on a separate phone call to speak with someone. The B FA & I waited on hold for 45 minutes; and were not successful in getting a hold of anyone to be cleared. In the meantime; the Chief Pilot gave the ok for us to be transported to the hospital (since we couldn't get a hold of anyone). This whole process of 'being cleared' to go to the ER took over an hour. Eventually the 3 Flight Attendants were transported to the Hospital by ambulance.




Synopsis: Airbus Flight Attendant crew reported a fume event during descent which lasted until gate arrival. Captain was notified and medical assistance requested. After much delay Flight Attendants were transported to local hospital for evaluation.
