The summer airline wars kicked off Friday, and escalated over the weekend, with Southwest Airlines kicking it off with $49 to $99 one-way fares.

The NBC affiliate in San Diego recently ran this video:

Other airlines jumped on the sale bandwagon. I was looking for a July flight from San Francisco to Minneapolis last week, and was about to buy a $350 round-trip ticket but decided to wait. Saturday night the price dropped to $189 round-trip on United Airlines and I snatched it up.

Airlines typically have summer sales, but this is the earliest that Southwest Airlines has started its summer sale, according to the NBC San Diego story.

So if you're at all inclined to travel this summer, best hop to procuring your tickets now.
