Here’s what consumers have asked with answers from OneTravel staff and previous consumers.
You will not get a ticket from one travel, or most other online sites. You should have received a reservation code with the email confirming your ticket purchase. That email has a code but it won't work to access the airline itself. You just print the email out and take that to the airline. I would call the airline directly and confirm your ticket is booked. I've booked quite a few flights from One Travel, and while there are some issues, the prices are great and I've never had a problem getting on my flights.
