Lowest airfare to la from phoenix?

http://southwest.com They usually have the cheapest around.

Southwest Airlines- www.southwest.com
Usually has really cheap fares from most west coast cities to Phoenix. Check out Ontario Int'l for some cheaper fares.

Also check out my travel site, especially if its a last minute trip since many Southwest fares require advance reservations. www.danbautravel.com

i'm going to also say southwest airlines.

i'm spoiled w/a bf working for U.S Airways so we fly free but before i met him anytime i needed to fly anywhere from phx-i always used southwest b/c it was cheaper.

try www.kayak.com - it's a search engine that pretty much checks airfares for every single site. And remember...airfares change quite frequently (like I think rumor has it if you go on at around 2 a.m. or something like in the morning midlde of the week, you'll find the cheapest rates) so what other people give you now may not hold up by the time you make your reservations.
