I logged in. The top right corner showed my 29k points. I searched for my itinerary, but got the same error message when trying to proceed with booking. After hours trying to chat with customer service, I accidentally stumbled upon a workaround.

1. When you browse to the Frontier website, the key is that you make sure that you're not initially logged in. Enter the desired itinerary in the search box on the home page and select that you want to pay in miles.

2. After you choose the itinerary you desire, the website should then prompt you for your login details. Proceed to book as normal.

Doing it this way, I did not get the same error message about insufficient miles, even though the top right corner showed the same 29k. I was able to book my 40k point itinerary successfully. Miles were deducted from my account and the other pooled members' accounts as expected.

Hope this helps someone!
