I am a software developer and trying to understand the aviation domain because I see some very interesting opportunities after seeing airlines adopting NDC standard for their distribution.
I am trying to understand the difference between an IATA number and IATA TIDS number which is issued by IATA which is also used for identifying travel agents globally. As far as I know that an agency has to pay very huge amount of guarantees to IATA to get an IATA number, but IATA TIDS is free of cost. What is the difference between them and what are the benefits of IATA which are not included in TIDS?
Thanks
