Going over my records I came across an ecert that I thought I had already used.

I did a quick search with the ecert # on .bomb and it's pulling up discounted flights as if the ecert was still good.

Hitting the "Select Flight" link brought me to the purchase page

I would've thought that's where it might have been rejected or would that happen at the next screen (actual time of purchase)?

If the ecert has been used, at what point would that register?

Aside from calling web support is there a better way to check if my ecert has been used or still good?
