No inside information, but probably by design. AA is a large company with a lot of resources and commits quite a bit of it towards base planning/manning.

In todays market (especially at NK for example) if someone cancels 3 or 4 days prior I don’t think they would have a problem filling that slot last minute if they needed too.

I also haven’t been in the schoolhouse for awhile but, there was a point in the not to distant past where guys were waiting 9 months after Indoc for the 737 type. That’s full pay day 1 at home, great for the NH, expensive for the company. I’m sure that weighs heavily on these numbers.
