	On 10 March at the 2015 Cheltenham Festival, Jezki attempted to repeat his 2014 success in the Champion Hurdle. His seven opponents included Hurricane Fly, The New One and the previously undefeated Faugheen. Starting the 6/1 third choice in the betting he moved up into second place behind Faugheen three hurdles from the finish but was hampered when the leader made a jumping error. He kept on in the closing stages without ever looking likely to win and finished fourth of the eight runners behind Faugheen, Arctic Fire and Hurricane Fly, beaten more than eight lengths by the winner. On 9 April was matched against Arctic Fire and the 2012 Champion Hurdler Rock On Ruby in the Aintree Hurdle over two and a half miles. He was held up by McCoy before moving up into second place behind Arctic Fire approaching the last. When Arctic Fire fell at the final hurdle, Jezki was left with a clear lead and won by thirteen lengths from Rock On Ruby, being eased down by McCoy in the closing stages. Harrington commented "It's great to get him back in the winner's enclosure. They've been hard races all season and he's been on the go for a long time but he was very tough today". Three weeks later he was moved up to three miles for the World Series Hurdle at Punchestown for which he started 5/2 second favourite behind Hurricane Fly. With Mark Walsh taking over from the recently retired McCoy he was restrained in the early stages before moving into fourth at the eleventh of the fourteen hurdles. He took the lead approaching the last and stayed on to win by one and three quarter lengths from Hurricane Fly with a gap of eight lengths back to Zabana in third.
