In the seventies the service from Dublin to Leeds and return mid afternoon was EI336/7. Call sign was Aer Lingus until probably early eighties - after I'd moved away so stopped hearing them regularly - by which time Shamrock had come into use. I don't think they were only airline to move away from using the company name, was one of the drivers possibly call sign confusion and/or need for brevity?
