Please post if you figure it out. Might be fun to take DS to.
I just found a date only at
www.ocairshow.com .
It's June 19 and 20, 2021. Saturday and Sunday.
Edit: found another site that gave more info. Google OC air show.
It's changed up from last year, with the beach divided into sandboxes for sale.
This is probably right in front of the Courtyard, Hyatt, Quality Inn, and Holiday Inn and Suites in the 15th Street to 17th Street area.
Last year the chair and umbrella guys set up chairs in a line around 7am and sold them as needed, plus would sell you a set to put wherever you wanted it. Looks like at least part of the beach is regulated this year for these sand boxes, which would be really nice except it says they are all sold.
Now, I'm not as interested if I have to walk to find open beach.
I booked 19th and 20th at the Hyatt anyway, pending getting more information. Points rooms were still available (20K). Cash rate is $519 plus tax, about 2.85 cents per point. This may get canceled. I also like to go near the end of July as I like to go to the Greek Festival they have at the convention center, assuming they have it this year.
