To be a TA and eligible for travel deals as a TA (and trust me when I say that the general public and pin offers at Disney are usually much better than a TA room), you must be with an
accredited agency and possess an IATAN card or CLIA card.
Both IATAN and CLIA have eligibility guidelines. For example, IATAN agents must receive $5000 in commission minimum each year to be eligible to purchase the card. CLIA has training requirements as well. The agency under which you are working must be part of CLIA or IATAN. You can visit CLIA's web site for the training requirements:
www.Cruising.org. CLIA cards are easier to get than IATAN, but many travel suppliers do not recognize the CLIA card (such as Marriott.) The IATAN is the "biggie" in the travel industry. If you have an IATAN card it shows the travel supplier that you are an active reseller of travel. Both cards are only valid for one year.
There are many places that claim to be travel agencies however they are just multi-level marketing opportunities so beware of an agency charging a large up front fee. It is a lot of work to sell travel, and it can take years to build up a business. Commissions are usually split between the host agency and the agent, and agents usually pay fees to sell travel. Many things a TA books do not even have a commission associated with them. Sometimes you might work for hours for a $24 commission that needs to be split with your host agency. It is tough to sell WDW and make enough money to support a decent part time job. Agents who actually make money selling travel (especially Disney travel) have been doing it for a while and have a good client base, and many repeaters. (God Bless the repeaters and their friends!) Agents must also continue their education to be credible, and it can get pricey to go to conferences.
Don't decide to sell travel for discounts as travel suppliers don't want to provide discounts for TAs--they want full paying guests. Cruise lines also have eligibility requirements to book a cabin as a TA with their line. An agent who sells tons of one cruise line may not be eligible to book as a TA on another.
FWIW.
