Spirit applied last week for the 14 unusued USA-Colombia frequencies to start daily FLL-BOG and FLL-BAQ. What they didn't realize is that they belong to AA, it is just that AA has not been using them. AA's response:

Even though AA is allowed to keep these frequencies dormant, there has been precedence (UA's unusued Brazil and Argentina frequencies) in which frequencies that are allowed to be kept dormant have been taken away from the airline. AA says they will use them by the end of the year, but if they don't show that they will be using them on a consistent basis (which they have not), they face losing them.
