Aircraft
Our pilots called shortly after departure; around 10;000 ft. They asked if we could smell anything out of the ordinary. I could not identify any smell in the forward part of the cabin. I asked B FA (Flight Attendant) if she could identify anything towards the back of the aircraft. She could not. The pilots informed B FA that they had donned their oxygen masks as part of their procedure to identify and try to eliminate the cause. Captain and First Officer (FO) think they eliminated it by switching off pack one. We continued. During flight; just after reaching cruise altitude; we gave the pilots a break. When I went into the flight deck; I could clearly smell something chemically; wet sock smell. C FA was guarding and said he could smell something off next to the Flight Deck. Our Captain and our FO said the smell had dissipated but was still there. Just prior to decent; we (B FA and I) gave the pilots another break. The smell seemed to still be there but less than before. Upon landing; the pilots informed us the smell returned about 5 min before landing and continued through taxi in. The Captain opened his window for fresh air during taxi in. We were only on PACK 2 at this point. Maintenance came on board after deplaning passengers and ran the APU and the whole AC immediately had the chemical wet sock smell. Maintenance then went through their procedures and cleared the aircraft to go. B FA and I both experienced stomach discomfort and itchy eyes; and B FA and C FA experienced headaches. Mostly dissipated by the time we spent off the aircraft.Maintenance cleared the aircraft; they frequently cannot duplicate. Maintenance personnel should ride the jump seat after these events for takeoffs and landing to as close as possible recreate the same circumstances.
