The Shamrock Club would gain a foothold in the Irish community by sponsoring and chartering flights to Ireland. These trips were very popular, and there were often multiple trips to Ireland each year. When the chartered flights program started, there was little in the way of direct flights to Ireland, and those that existed were often prohibitively expensive. Changes in the federal laws would take the Shamrock Club out of the charter business, as more commercial airlines saw the growing interest in Ireland to be a viable money making option for them.
