It looks like Worldspan doesn’t work on the old Windows XP anymore.
This is starting from 15 May 2018.
When you launch the program, you will get a basic error from Internet Explorer, saying that there is no connection.
If you try to load other websites, you will notice that 80% of them will not work or they will partially work.
This is due to the fact that Windows XP is very old and so is the latest Internet Explorer version that works for this operating system, Internet Explorer 8.
The best thing to do is to buy a Windows 10 licence and install this operating system.
Worldspan works flawless on Windows 10, you actually don’t need any settings to run the program.
If you have any questions, please leave in the comments.
