Use a Catalog (or in Word XP and later it is called Directory) type mail
merge main document and in that document set up your ticket as a one row,
two column table.  Insert the desired text into each of the cells of that
table and insert a merge field from the data source that contains the
numbers of the tickets in the required place on each of the cells.

There should be nothing else on the main document apart from the table
mentioned above.  Then, when you execute the merge to a new document, that
document will contain a table with a row of cells representing each ticket.

The easiest way to create the data source for this is to use an Excel
spreadsheet in which you create the numbers by typing in the first number
and then use a formula in the next row that adds 1 to the number in the row
above and then copy that formula down for as many rows as you require
tickets.
