If the CO web site let you do that then it should be good (although I wonder if they made a mistake in allowing this when they could have extorted more money out of you

). But to be on the safe side, I'd print out the fare basis/rules for each flight and examine them closely to make sure you're not going to break their rules (even if the web site allow you to book this kind of ticket). Just being paranoid, I guess.
Good luck!

It is straight from Continental's web site. If I book each trip round trip it will cost $2000 for both round trip tickets. If I book one multi city ticket (four flights total) its will cost $560.
@deubster
It is end on end, but going back and forth. I am not buying two round trip tickets that overlap. I am flying the entire ticket from begining to end.
@UA_Eagle
Continental is the only airline that has non stop between A and B. So I don't have a choice with whom I fly.
Thanks for the replys All!
