If you happen to be in Arizona and the Tucson area, the USAF Heritage Flight Conference occurs the first weekend in March. It’s quite the air show with WWII fighters and the new jets flying various formations during Friday through Sunday. If you have base access, you can get on the ramp for the “petting zoo” early each day before flying starts. If no base access, there are numerous places around base to watch, the Pima Air Museum being a prime spot off the east end of DMAFB.
Additionally, the demo teams (F-16, F-22, & F-35) practice their air show routines everyday.
