Deduct airfare and other expenses related to study abroad?

My husband, a full-time grad student in Ohio, spent one semester studying abroad at a university in Chile. Can we deduct his airfare and living expenses on our tax return? I stayed here and paid 100% of costs of household, but additionally we had to pay rent, groceries, etc. for him while he was gone. How should we handle this on our return?

It doesn't go on your return. These are personal expenses.
