Offering a cola is not a big deal. They will occasionally send one out for a month or whatever the system litigates. There are plenty of pilots that will jump on it. Some pilots have Doctors for a spouse, heck yeah they'll take a month off! It's just a handful of spots. Operationally they see a opportunity to alleviate a few salaries for a short time. They are all about the money, big or small. The hiring will continue strong.
No worries.
