Punki,
Been through this a lot lately.
2:00 PM departure your looking at 15-20 min. including security. Give yourself a half hour.
The other big varible is Alaska (the State) tourism season from LA is huge, the early AM is a mess and basically everyone is tyourist class, w/ little or no knowledge of modern security requirements so you get a lot of fishing hooks being removed from hats......
Good Luck, the terminal is a dump.
