How to merge multiple files to one, placed next to each other in Illustrator CS6

Question

I have bunch of QR codes and bunch of serial numbers associated with these codes. I need to print a lot of tickets, each having different QR code and corresponding serial number on them.

So far I had success to generate those tickets, by using variables and datasets, with help of this awesome tutorial https://www.youtube.com/watch?v=eCBrK8tZAXQ and the script mentioned in it.

I end up with hundreds of files, each having one artboard, with one ticket in it.

What I need is a file with artboards of A3 size so I can create a PDF file with multiple pages for print. Obviously on each of these A3 artboards should be as many tickets as possible.

Not sure if it'll work for you, but you can create a multi-page PDF merely using Acrobat...

In Acrobat, choose File > Create > Combine Files into Single PDF and choose your separate .ai files. They should be combined into a multi-page PDF.
