Frontier Airlines has started to become the airline most known for offering "spur of the moment" deals, and they have a new one which could definitely save you some money if you work the timing right.

Here are some particular rules to follow with the latest fare offering from Frontier Airlines:

- Tickets must be purchased by 11:59pm on April 16th for domestic nonstop travel

- Travel must occur on a Monday, Tuesday, Wednesday, Thursday, or Saturday

- Travel must occur sometime between April 30th and May 27th

Of course, you'll want to play your cards right as Frontier Airlines also charges for both checked and carry on baggage. And if you want to be able to pick your own seat, that will also be an extra fee.

Here are the deals you can take advantage of when flying out of Denver:

- Denver to San Diego: $49 one way

- Denver to Phoenix: $39 one way

All in all, if you're looking to take in the sunshine of Phoenix or the sandy beaches of San Diego, this could definitely be the right deal for you!
