I booked on Frontier once. The credit card company ended up refunding the ticket price agreeing that how the airline tried to treat me justified me re-booking on another airline. Never again.
Hundreds of planes, thousands of crew. Go try Untied, or AA, or Delta then. Frontier folks are family and we treat guests with courtesy - how do we know you might be having a bad hair day? Look at all the idiots we have to put up with a smile.
