Narrative:

Location: lga airport. After landing at lga, first officer dialed wrong frequency for ground 121.9. Jfk ground answered our call and cleared us to the gate. We taxied ahead approximately 150 ft after first officer made second call and we were again cleared to the gate. We had only moved about 100 ft when we realized we were on jfk ground frequency instead of lga frequency. Controller at jfk realized about the same time and we switched to lga ground. Lga ground said there was no conflict. But I thought it should be known that if you land at lga and use 121.9, jfk can hear you and they might clear you to the gate without knowing who you are or where you are.
