i am hoping to travel to new york with my 6 month old baby. my sister will be travelling from ireland and we would be staying in newark. she is flying into newark. i can get really cheap flights from man to jfk and would like to know if its possible to travel cheaply to newark from jfk or should i just pay the extra £100 and fly into newark? im more concerned about the trip back to jfk with heavy bags etc .
