Only if the unable to travel due to covid extension is still available. Otherwise you'll need a proper visa.
The easiest way to prolong your stay is to get a tourist visa before entering Thailand, this is for 60 days instead of the 30 days the visa exemption gives you.
yes, then if the 60 day option for having a Thai family is available then it avoids the need to apply for the non-O. I'm not sure on the 60 day option here so will leave someone with more knowledge than me explain.
Alternatively, visa exempt for 30 days then apply for the non-O in Thailand to give 120 days
OK, in which case if you want to stay for 110 days don't apply. Either arrive on visa exempt or apply for a tourist visa, you have a choice to then either extend this by an additional 30 days in country and/or or apply for a non-O once in Thailand. This takes you beyond your 110 days.
Someone may also correct me if I'm wrong but I believe there's also a 60 day visa available for having a Thai wife but as I'm not 100% certain on that I'll leave someone like Tod to clarify that should he see this post.
OK just seen you've changed it to show leaving Thailand and not entering as I thought you were trying to do.
In which case, can't they put you on an earlier flight? If they can't, and you have to leave on 30 November, then you'll have to book with another airline.
Alternatively, if you can leave on 1 December then you can always apply for the unable to travel due to covid extension to cover the additional day so you don't get any comment put in your passport.
