I would recommend using ITA Matrix or an online travel agency (Expedia, Orbitz, etc.) to become educate yourself about the various airlines' route options, and to get a sense of prices. You are wanting to travel at a peak season, so lower fares may be a challenge.
You also might want to explore options for accruing mileage to use for award seats, with the same peak-season caveat (availability will be a challenge).
Take a look at the
http://www.flyertalk.com/forum/trave...ools-here.html thread and wiki for more resources to help you get a basic plan.
Once you've done that bit of homework, you might be able to post some more specific questions so FTers can be of greater assistance.
Good luck!
