Oh, come on, guys, help a guy out already. Geez! Telling them the fare without giving information on where to get it is rather useless, don't you think?
I have two suggestions. National offers a roundtrip fare from Las Vegas to Newark for $278; if you're planning on renting a car on this trip, you can get off in Newark and drive to Albany. National's service is supposedly really good, and it's on 757-200 aircraft.
My other suggestion is that you join the Best Fares travel club, which can be found at www.bestfares.com. It costs $60 to join, but they have airfares that are $100-200 lower than the lowest fare even on Expedia or Travelocity. They'll jerk you around a little bit with service fees, and you'll have to spend an hour and a half on hold listening to the same 10 songs over and over, but IMO, it's worth it. Plus, once you've paid the $60 subscription fee, you'll be able to get whatever other tickets you need for the rest of the year at reduced rates. Check their website for details on what fares are available.
Hope that helps!
