I have one for $1.90 that's been in my account for a while. Same exact situation - no tick box. I can't remember what I did - - maybe I entered the number manually, but, one time I actually got DL.com to say something like - - Name Mismatch.

I have a feeling it has something to do with the placement of my middle initial - I dunno!

I don't understand how the name wouldn't match if it came from a ticket with my name on it, also booked on DL.com!

Good luck!
