Narrative:

En route to bdl at FL290, received a TA at 12 O'clock. Shortly after, received an RA that instructed us to climb. Had traffic in sight, but followed RA. Traffic was climbing from FL270 to FL280 at a high rate. ZOB did not issue traffic instructions. We were talking on 135.77 over jhw at XA24Z. ZOB later apologized and said they would file a report on the incident. It was my first time to receive a RA at cruise altitude.
