That Aires application for BOG-FLL, and from other Colombian cities to FLL had Spirit fingerprints on it!
It seemed odd that an operator that has no jets, would apply only for routes to FLL. It did have the decoy that it might be operated with a B737 or MD83 series or Airbus A319, leaving some room for doubt.
Aires has been given 7 weekly frequencies on the BOG-FLL route, with others pending expansion of the bilateral agreement.
Well, it has now come out that Spirit's director of communication, Juan Arbelaez, is an old mate of Aires CEO and they have been working together for 3 months on the Colombian routes project, presumably when AA put a spanner in the works by retaking some dormant frequencies that NK had hoped to get. So the Aires application was designed to be operated by Spirit all along.
Aires has 6 months to get the route started, and the operation by a third party still has to get approved, but the old mates appear confident..
This is the article (in Spanish), which has a few factual errors (such as saying that DOT had approved Spirit's application in the first place and that it was Aerocivil that did not), but I am sure the essence of this new alliance comes through alright.
