Wanting to get regular season tickets for a single game in 2022 when will they go on sale?

So Basically the title. Im trying to buy tickets for my dad for his Christmas present this year but can’t find any info on when tickets go on sale typically or how much they go for. I see on the Astro’s site that the tickets aren’t up yet but some 3rd party sites like ticket city already have them up. Are those third party sites just ahead of the game or something or are the 2022 regular season single game tickets not on sale yet? I’m looking to get him like 4 tickets and spending like $40/ ticket is fine. Any help is greatly appreciated. And let me know if this isn’t the sub to ask or if I should post somewhere else. Thanks a ton!
