I have been sort of ignoring it because at some point (when it was all still working) I had my Citi Prestige card added to my saved payment methods, and that has been working fine ... until today. I went to buy a DEL>BOM ticket, got it all set up,etc, went to the payment screen, selected my saved Citi card radio button, and then 'boom', the Indigo website wants me to add my address on the next page. I did, and of course the "Pay" button stayed grayed out.

I ended up just buying through an OTA to get it done, but does anyone have a solution? I prefer buying through airlines directly, especially Indigo, because I like to get the Super6E fare, for the XL seat and extra kg's of luggage, and I usually add Fast Forward.
