Looking ahead to easter holiday, and good friday weekend, I am planning a trip and need the help of fellow AC FTers.

YOW-LAX-YHZ-YOW

I would like to travel on Saturday am to LAX, stay there until Wed., break my journey in YOW for about 20 hours then fly out to YHZ, stay there for about 4 days, and back to YOW on the following Monday pm.

My question is how do I book the above, and is it any cheaper or expensive then buying two tickets: a. YOW-LAX-YOW; and b. YOW-YHZ-YOW.

I thought it would be easier to buy YOW-LAX-YHZ-YOW, and then call AC, and tell them I would like to break the journey in YOW en route to YHZ for about 20 hours.

I would highly appreciate advise on the above.
