I had this issue a few weeks ago with no check box (tried multiple browsers), and had to call to get a TCV applied. I clearly explained that I had to ticket on the phone because delta.com had an issue. When the agent was done, she has the price with the $25 ticketing fee. She gave me this song and dance about how she might be able to have it waived, but it would require a supervisor and that would be a pain for both of us, and wouldn't it just be easier if I paid the ticketing fee. I said no way, get the supervisor. It took about 5 min to get the fee waived.
