I wouldn't even consider making DD go out of town the weekend of her high school graduation. There will be a ton of events for her and if Frontier is really the only flight they are not a dependable airline for something like this. It's unfortunate for sure that both are the same weekend but missing HS graduation should not be an option.

Am I reading it right that he isn't technically graduating from the program in 2027, because he will still have to do his final internship year? Does that mean he could choose to walk a year later in 2028?

If his highest priority is having everyone at the ceremony, maybe he would consider pushing back his graduation. I know you said he won't be local that year but there's no reason he couldn't travel for it.

I was also wondering if he has a different grad-related event coming up that you could be there for. When my husband finished grad school, he invited one parent to his thesis defense and one to the graduation... they were something like 6-8 weeks apart so totally separate events. His parents don't get along (which they had recently demonstrated at our wedding) so it was nice to be able to celebrate separately. Not everyone would see it this way I'm sure but I personally think the thesis defense was more meaningful.

I think you DEFINITELY should attend your daughter’s graduation 👩🏼‍🎓 ceremony.
No exceptions.

For your stepson, I think either a.) his Father should fly up to attend or b.) your entire family can fly up either the wknd before or after to celebrate.

But I firmly believe that your daughter’s graduation should take full precedence.

Hope you guys can find a mutually beneficial plan for everyone!
