slug Link redirect to subdomain?

[Leviiii]

Hi !
Im Levi new here and new in the world of SEO, please dont judge if my questions are silly.

Back on the days when the site was built we thought it is a good ideea to have subdomains that together with the domain name represent our main keywords.
ex. https://stansted.tonorwich.uk, https://heathrow.tonorwich.uk, https://luton.tonorwich.uk, https://gatwick.tonorwich.uk.

There is content on this subdomains, would it make any difference from SEO perspective if we create slugs that redirect to these subdomains? for example creating https://tonorwich.uk/taxi-minibus-vip-tesla-norwich-to-stansted that redirects to https://stansted.tonorwich.uk ? Or better create these slugs with slightly different content?
Any ideeas would be appreciated.
Thanks in advance!

@Leviiii actually if you are solely creating slugs that redirect to the subdomains, then there is little value in this action? Would be better off just having the subdomains linked from your main domain directly. Better for both users and search crawlers.

Alternatively, if your slugs have different content and then you can link to the corresponding subdomain. *Note that its a normal href link and not a redirection. If you are worried about content duplication or keyword cannibalisation when doing this, can simply point a canonical tag over from the subpage to the subdomain.

The first option displays the same content on one URL as it does on another. For example, if you recently changed your domain to DomainB but still have a large number of visitors to DomainA, you could use this to show them all of the existing content that is located on the new domain without having to update both websites.
