Aircraft
During approach I thought I smelled an 'oily' scent. No one else in the crew complained of any unusual smells so I thought it might just be my imagination. Being curious; I asked the F/O (First Officer) if he noticed anything unusual. He said he caught a whiff of something. We were on final approach and landed the aircraft. At the gate I asked our #1 F/A (Flight Attendant) if she noticed any unusual scent and she said no. I then asked the F/A working in the back of the aircraft and he said he smelled a chemical odor during descent.
A320 Captain reported smelling an 'oily' odor in the cockpit which was also reported by flight attendants in the aft galley.
