Can I book a one way ticket for my wife coming into Columbus from another country
Booking a ticket for your wife whose journey originates from another country is not an issue. The airlines will ask for details of the passenger as well as the person paying for the ticket (if you are not paying cash).
Once the ticket is booked, the information can be transmitted to your wife. However, a solid identity proof will be required to collect the ticket. You can also check in the passenger electronically, and the travel papers like passport and visa should be adequate for international passengers in particular.
You will find plenty of useful information on one way tickets at this web site:
