Frontier Airlines is running a one-day promotion, with one-way airfares starting at $19.
However, these rock bottom prices come with many terms and conditions.
To take advantage of the prices, you must travel on a Tuesday, Wednesday or Saturday from September 29 to December 14, excluding Thanksgiving week. You must also be a paid member of the Frontiers Discount Den membership program. There is a surcharge for hand luggage and seat assignments.

Still, if you can find times and destinations that work with your schedule, and can navigate the surcharges, these prices represent a great opportunity to take a cheap fall vacation.

Example of flights
Frontier offers only $19 tickets on certain routes and dates. To find a summary of available routes on Frontier’s website, search for sample routes from your chosen city or click on Frontier’s “Offers” menu tab, then enter $19 in the “Budget” box. If your city appears on the menu, click the “Book Now” button to get one of these super discounted tickets.
The promotion indicates that you must be a member of the Discount Den membership program to use the $19 prices. However, TPG found several routes offering $19 fares for the general public.
Before you book, be aware of potentially large surcharges for seat assignments and baggage – even for hand luggage. You must click through the booking process before additional charges are disclosed for the flight. Prices can be $60 for a single carry-on and $50 for seat assignments.

Phoenix and Denver to Las Vegas
Looking for a super cheap Vegas vacation? The screenshot above shows several October dates when Frontier is offering $19 fares to Las Vegas’ Harry Reid International Airport (LAS) from Phoenix Sky Harbor International Airport (PHX).
In this case, the price is available to both the general public and Discount Den members, so there is no need to sign up for the program. Return flights are available for the following Tuesday multiple times throughout the day, so you can actually use this price for a week’s vacation in Vegas.
Likewise, you can find flights for $19 in mid-October between Denver International Airport (DEN) and Las Vegas, with no requirement to join the Discount Den club. The $19 flights tend to be early in the morning or later in the evening, but if you shop fast, there are still some attractive flight times available on select routes.
Chicago to Los Angeles
One of the best values in Frontier’s sale is the $19 flight between Chicago’s Midway International Airport (MDW) and Ontario International Airport (ONT) outside Los Angeles. The $19 price is only available to Discount Den members, but the public price of $29 is still a great deal to fly non-stop across the country. Although these are not the main airports for Chicago and Los Angeles, the extra commute may be worth your time to save possibly hundreds of dollars on a flight.
The available dates on this route for the $19 fares are more limited than in other cities, with only one date appearing in early October. But if you can find a couple of dates and times that work for you, this is a reasonable chance to escape Chicago’s fall chill for some Los Angeles sunshine.
Maximize your purchase
If you book this deal, don’t forget to use a credit card that gives bonus points on airline ticket purchases, such as Platinum Card® from American Express (5 points per dollar on airfare booked directly with the airline or through American Express Travel, up to $500,000 on those purchases per calendar year). Or try Citi Premier® Card or Chase Sapphire Reserve (both 3 points per dollar on airfare). You can also use Chase Sapphire Preferred Card (2 points per dollar spent on travel). For more ways to get the most out of your airfare purchases, see this guide.
The bottom line
You can’t beat Frontier’s $19 price sale for cheap tickets. This one-day special is worth your time to find some great fall vacation spots.
But remember that these prices come with many terms and conditions. You must be a paid member of Frontier’s Discount Den membership program, you must fly on a Tuesday, Wednesday or Saturday, and you must pay (sometimes substantial) surcharges for seat assignments and baggage.
Even if you’re not a member of Frontier’s membership program, $29-$39 non-member one-way tickets represent great deals—and some $19 fares are also available to the general public.
So if you can find Frontier flights that fit your schedule and can do without a bag, you should buy some of these flights to take some ultra-cheap fall trips.
