While at FL 350 the flight attendants notified us of a rubber burning smell in the forward cabin . They stated the smell lasted for about one minute. The First Officer went back to the forward cabin area to assess. He did not notice the smell; queried some of the passengers for any input and concerns. There were no ECAM indications showing a problem. We continued on to ZZZ and notified Maintenance.
At FL350; the lead Flight Attendant called the Captain and said she smelled a burning rubber odor. The Captain instructed me to go back to the first class cabin and investigate. After one of the flight attendants came in the flight deck; I went back to the first class cabin and forward main cabin and did not smell anything. I spoke to the first class cabin passengers and they said they did smell a burning rubber odor but it lasted only a minute. I went back to the flight deck and reported back to the Captain. We continued to ZZZ and landed without incident. The Captain spoke to Maintenance and the outbound crew about what happened.
