Ways to Score Deals and Discounts on Southwest Flights

To save money when flying with Southwest Airlines, it is all about being a smart traveler and availing oneself of the many programs and promotions they can offer. Southwest Airlines, unlike other airlines, has some peculiarities, though, which can be exploited. You can get deals and discounts on your next Southwest ticket in the following way:

The Low Fare Calendar and Fare Sales

The Southwest low fare calendar and Fare Sales are the two major steps you can take to get the low-priced tickets from Southwest Airlines. If you explore them, getting the cheap flights will become easier and convenient. Let?s discuss how you can explore these two: 

• Fare Sales: Southwest has a reputation for daily price promotions. Such sales can be very attractive in terms of discounts and normally are announced at short notice and have time limits. The best tip to keep up with these is to be on their list of emails and follow their social media, because it is posted there.
• Low Fare Calendar: It is one of the strongest tools that Southwest offers to book flights on Southwest Airlines. Do not look at specific dates; instead, check the Low Fare Calendar on their site, which shows the cheapest prices to any destination throughout a whole month. On most occasions, travel dates are flexible, and a one-day or two change will save you substantial amounts.

Rapid Rewards Program and Companion Pass

Rapid Rewards is one of the main money-saving opportunities, where a consumer will receive a specific number of points per flight that are exchangeable for further transportation. The ultimate prize in the minds of many participants in the program is the elusive Companion Pass, in which one person of your choice is allowed to fly with you at no additional taxes and fees.

• Rapid Rewards: The free loyalty program, Southwest?s Rapid Rewards, has to be enrolled in. Whenever you book southwest flight and fly, you earn points on that flight, and these can be redeemed later on to make a reservation on a non-blackout flight.
• Companion Pass: It is the most useful one in the domestic flights, presumably. Whereas you can bring a companion (not including taxes and fees) with you on any flight you fly, but there is a condition that you have to have earned a certain amount of qualifying points within a year, and you will be able to obtain such a free ride in a maximum of two years. A popular way of earning the Companion Pass is by accumulating sign-up bonuses via Southwest Airlines co-branded credit cards.
• Cash + Points: So, what will you do when you do not have enough points to cover a full reward flight? Southwest will also find out that a combination of both cash and points is acceptable when purchasing your fare.

Booking and Travel Strategies

Some might think that traveling within a budget with Southwest Airlines might be a challenge; however, you can always make the journey cheaper. You just have to be aware of certain low-cost strategies, such as: 

• Booking Early: It does happen that fares are cheapest at the time a flight schedule is published. Sometimes it is wise to make the booking several months ahead to obtain the best price.
• Flying Mid-week: Tuesdays and Wednesdays are the best time to book flights and the least expensive days to fly because they are not as busy as the weekend.
• Check and Rebook: The rebel bubble has a very consumer-oriented policy. When you make reservations on a flight and flight prices go down before your departure time, you can rebook the flight at the new, lower price and have the difference returned to you in the form of a flight credit. Checking the fare of your booked flight now and then is really a great habit.
• The Benefits of the Credit Cards: Southwest-branded cards include benefits in addition to earning points with many of them. They might be offered as anniversary bonus points, free checked luggage, and other traveling amenities that will total an enormous amount of savings.
