Gem,
The online travel system is the internal method used to raise paperwork for sign off. We still need to call our travel agent to book flights etc. I think there might be a new system rolled out for that too.
When more of us begin to use the system I am sure more questions will be asked.
It's strange how IT have just replicated the Word template we have been using to an online version, without any input from the user to ascertain what is required and what isn't. An ideal opportunity lost I think.
