As someone who knows enough about this subject, I have decided to post this as a warning, I guess you could say, about the buying and selling of Southwest Airlines Rapid Rewards tickets. And yes, they are tickets, not vouchers. Read on, my fellow eBayers....

eBay developed the Verified Rights Owner (VeRO) Program to facilitate cooperation between eBay and rights owners protecting their intellectual property rights. Southwest Airlines is a member of this program, and has the right to pull any auction it sees fit. If you post a listing for a Rapid Rewards ticket/voucher, it can and will be pulled. Southwest Airlines also lists this underneath their rules and regulations, available through southwest.com.

Rapid Rewards Awards are transferable; however, the Awards and Drink Coupon Books have no cash value and are void if sold, purchased, brokered, or bartered. All transactions in the Rapid Rewards program are subject to review and adjustment by Southwest Airlines. Southwest Airlines will cancel your account, Awards, and any associated reservations if misuse or violation of Rapid Rewards rules is detected. It is also against Rapid Rewards rules to offer to buy or sell Awards via Internet auction sites or classified advertisements, whether the transaction is completed or not.

eBay does have it's own rules and regulations regarding the sale of travel items. Many sellers will post an abbreviated version (see below) in order to try to allow their listing to remain. Some sellers will post it as a mandatory rule, aka "As per eBay rules the following must be stated..." Check out the above link, in no place does it say the rules must be repeated on every auction. This means pretty much nothing as far as the sale of Southwest tickets/vouchers are concerned. In fact, just about every airline is also a member of the VeRO program. (Sellers, please read.) Posting this information does not make it a valid listing, no matter how the seller tries to validate it. Yes, Southwest Rapid Rewards tickets are transferable, but that does not mean that they are salable. Transferable means that the voucher does not have to be in the name of the person who earned it. It does not mean that it is yours to do what you please. By signing up for a SWA Rapid Rewards account, you are signing a contact. Part of that contract is that you must abide by the rules and regulations. And yes, it does say that tickets are non-salable. Any questions, go ahead and read it again. You do not have the right to sell another person/company/entities' services without their permission. SWA has actually filed lawsuits in the past because of people illegally selling tickets. (I won't even got into the fact that copying parts of other seller's auctions is strictly against eBay's rules, yet just about every auction will list the following.)

"This auction follows all Ebay travel guidelines: (Not really, this "disclaimer" means ABSOLUTELY NOTHING.)
1. I am and individual and not employed by the travel industry (I am not in the business of selling travel services)
2. I only deliver the listed item and provide no other travel services
3. I list only one of these items per month (I have not listed any travel-related item this year) This is not always true, yet sellers will say this on every listing.
4. This is not a travel club membership or "choice" travel certificate

I am not in the business of selling travel services, but simply wish to sell an unused travel voucher that I am unable to utilize myself.  According to southwest airlines, this travel voucher is fully transferable to anyone. Again, transferable does NOT mean salable.

Specific rule states: Individual travelers who are not in the business of selling travel services, but simply wish to sell an unused air or sea related travel voucher or gift certificate, may do so no more than one trip per month provided that the item is not a travel club membership or "choice travel certificate" or related item.  In such instances, the seller may play no role in arranging any travel other than delivering the item."

If you do choose to purchase a Rapid Rewards ticket, please keep the following on mind:

• You have no proof that the seller is actually selling you a Rapid Rewards ticket. He/she could simply be collecting money from you, up to $500, and purchasing a regular ticket for you at the lowest fare. Why, you could have done that yourself! And when it comes time to make a change, you have to pay extra.
• When eBay pulls a listing, before or after the sale is completed, any transaction is null and void. If you decide to continue with it, eBay has no liability to help you if you come into any problems. If you have already paid and the auction is pulled, there is not much recourse if you never receive your ticket. And don't expect Southwest Airlines to help you either. You will just be buying your ticket again.
• If and when Southwest Airlines is aware of any wrongdoing with a Rapid Rewards account, they will cancel the account, Awards, and any associated reservations. Which means, you get to the airport to check in for your flight only to find out that you reservation has been cancelled and there is NOTHING that can be done, other than purchase a full-fare ticket. Think about it.

The information following comes from Southwest's blog, posted by one of SWA's security specialists:

A big part of the Holiday Season is visiting family, and travel is a popular gift.  As a member of Southwest’s Security Team for the past seven years, I want to make sure you have all of the facts to consider when making your buying decisions this year.

I have talked with countless Customers who chose to purchase Southwest Airlines’ tickets (paper and electronic), southwestgiftcardsTM, and Rapid Rewards Awards from unknown, unaffiliated third parties or from a “friend of a friend”.  Far too often, the victimized Customers are left stranded at the airport because they chose not to deal directly with the airline or a known travel partner.  When I ask them, “Who did you pay?” the response is usually someone other than Southwest Airlines.  Several recent cases I have investigated involved people who wired money to unknown third parties in Indonesia and Russia.   When I ask why they chose to purchase the reservation or the southwestgiftcard from an unknown third party, the usual response is, “To save some money.”  While there is nothing wrong with saving money, especially around the Holidays, people who respond to ads like these often end up paying for the trip twice, or jeopardizing their travel plans altogether.

For those who just can’t seem to let a “too good to be true” bargain pass by, it is important to understand the risks involved when responding to an unknown third party that posted a random ad on the web or in a newspaper.  Below are some Southwest Airlines’ policies and important tips that I would like you to remember when you are shopping/surfing for discounted airline travel.  These policies and tips will help prevent your travel from being interrupted.  

Should you purchase a reservation, a southwestgiftcard, a Rapid Rewards Award, or a travel voucher from an unknown third party, we can not guarantee the validity or security of that purchase.  If you have any concerns about a questionable advertisement or sale related to Southwest Airlines, please contact us directly.  I would like for every current and potential Southwest Airlines’ Customer to have a positive experience during and after their reservation purchase. Just remember, if an advertisement from an unknown third party catches your eye and it “looks too good to be true” then it probably is!
