Other reasons for failed online check-in are that you are on the TSA "selectee" list, or you're traveling with an infant, or the only available seats are emergency exit rows, or some information is missing from your reservation, like birth date (now required for TSA).
I am not in a mood to cut Frontier any slack. Even if I cannot select seats on the Frontier system for the Midwest flight, since that is the last of my three flights tomorrow why could Frontier not at least let me check-in and select seats for the first two flights?
For the record, I am not on the selectee list (I believe there is only one other person in the country with the same first and last name combination as me). I am not traveling with an infant, seat map shows lots of other seats unselected besides the emergency exit row (at least right now -- when I get to the airport tomorrow, who knows?), and I supplied my birth date.
