Anyone has seen similar thing? Has this happened before?
I am having exact same problem! Trying to book flights and it just hangs and then times out after you click to apply the credits. I messaged Frontier Care on Twitter yesterday afternoon but still no response. I'll let you know if I hear back from them with a resolution. Please do the same. Thanks!
