I know. :-(
But I booked the outbound now and I have 24+ hours to find a mileage return, or decide to cough up $100 for the Frontier return on 2/5 (or cancel). Even for $130, its still a good deal r/t to Miami, especially this time of year!
Though it is more expensive than my $30 trip there a few weeks ago, (for which they issued me a $30 credit because of the delays without me even asking!)
