Interesting article with quarterly fleet change info. Of interest is the net UAL RJ reduction year over year is forecast to be only 7 aircraft. I'm not sure if these numbers are after the "sky is falling" so we're closing the CLE hub due to the pilot shortage, or not.

Also, AK plans to increase capacity 7% with a forecast 1% cost increase. That should be interesting.

US airline majors to add capacity despite unit cost rises. Is "capacity discipline" history already? | CAPA - Centre for Aviation
