What I like best is being able to access the IATA bill at the last minute, instead of a couple of days in advance. It also allows for me to get the most out of my rewards. I wish there was a better way to access my account, it is easy to lose track of the password. I use the BSPlink to access my IATA rewards account. I use this software to process all of my airline rewards. This software allows me to access the IATA account at any time and it also allows me to track my points at anytime. The ease of use of the software, the ability to send out invoices so quickly and the ease of access to the accounting system. Nothing. I would like to be able to use the software on my smartphone, but I have not been able to do so. We are able to send out invoices for our clients within minutes and the accounting system is easy to use.
