Today is round two of JetBlue's "cheep" fares on Twitter. Launched last week and already nearly 10,000 followers strong, word is out on these ultra-low fares. The "cheeps" are announced each Monday morning at 10am and are for one-way travel the following Saturday. The catch? You'll have to pay the regular fare for one leg of your trip. Still, the super-low one-way fare significantly decreases the total cost of flying.

Staying on top of these "cheeps" and being decisive is key to snagging one-way fares for as little as $9. I considered taking advantage of a $9 Portland to New York fare for this Saturday, but delayed on making a decision and ultimately missed out. There are between 25 - 50 seats allotted at the rock-bottom prices and once they're gone, they're gone. This morning's sale included:

Long Beach to San Francisco - $9

Burbank to Las Vegas - $9

Portland (ME) to New York - $9

New York to Washington, DC - $9

Fort Lauderdale to Charlotte - $19

New York to Denver - $39

Boston to Antigua - $49
