They have plenty of flight time, more than enough to upgrade. They also are already typed in the airplane due to previous endevours. If the chalks thing works out, then they will probably upgrade, if they are willing to commute to Florida. However, they were also promised a denver base a few months ago, which never solidified due to other factors. Id just be cautious of the CP telling you that upgrades have been down to 5 months lately, because that is certainly not the case as far as Im aware. They are building a pool of those numbers, but like anything else in aviation, dont believe until your sitting in the airplane getting paid for it. Thats it.
