Frontier Chat has become basically unusable
I needed help on a 5+ hour Frontier delay yesterday. The Chat function is set up to discourage chatting. If you figure out a way to get into the agent queue, you will have about an hour wait for help, at which time you are likely to be disconnected before you get help.
Frontier will not last 2 more years if they don't fix this. In the meantime, I would encourage a DOT investigation. There needs to be a plausible means to contact your airline and get assistance.
