Hoping for you! If you're looking at Alaska, remember that the travelers can get a travel credit if the price goes down after it's booked. And their prices do seem to bounce around quite a bit.
If she has some flexibility with dates (b/c the fare can be very different from day to day), be sure to check out Alaska's flight #16, the one that leaves at 8am and arrives at 4:30ish. Not only is it a non-stop flight (lovely) but you get to the airport just in time to think about having a manicure at Butter:London and/or a massage right next door to Butter (and just steps away from Starbucks). IMO it's a perfect way to use the time before a flight.
ETA: rather than Orbitz I personally like kayak if you want to check a bunch at once. But mainly I just have each airline's main booking page saved in a file on my toolbar and I run through each of them really fast. ETAagain: and SW of course. But I find that SW just doesn't have the fares I like or the routes that make a fare worth it for me.
