How to handle one-off expenses that eventually be reimbursed?

Hi there everyone,

Brand new YNAB user here, but I love what I see so far. I had signed up a few months back but only really started looking at it yesterday. Pretty steep learning curve, but YouTube helps.

First big question... I like having my accounts linked, because then I feel like I can't hide anything from myself. But I'm having an issue with a couple of 1-off expenses yesterday that I won't be budgeting for... Namely my daughter's airfare home from university for the Thanksgiving holiday. Technically, this is eventually going to be zero charge to me anyways, because I will submit the expense for reimbursement to her My529 account. But that's going to take 4 or 6 weeks.

How do you recommend I categorize this expense now?

Thank you!
