Ok good to know... I called Frontier Airlines and they told me to talk to a supervisor at barclays. called barclays back, got someone who knew what they were talking about and told me the miles would post within 30 days of february 28th, so by march 28th. if they are giving me the run around we will see but i'll be patient for now

at least they confirmed I qualified for it.
fyi it's called the Frontier Celebration promotion, is what they said on the phone. some of the barclays people don't seem to know much about the promos though (probably just taking CC app info over the phone)
