What is the etiquette when inviting a friend to a wedding?

I have been invited, plus one, to a distant wedding. I will be taking my ex-boyfriend, now friend. What is the etiquette in terms of payment? He lives in a different state so we'll be meeting up at the location. Do I pay for his airfare and hotel?





Also, I want to make a longer vacation out of it, but he's not sure he can and if he can't it's not like I can make a quick trip to the airport to drop him off and continue my stay because the wedding is nowhere near an airport. What does etiquette say about that? Thanks!

I'm sure there is no "etiquette" for this. If he has agreed to go with you to the out of town wedding then he should know the costs expected with it. If he doesn't want to pay, then he doesn't go. Also, he should be responsible for his own transportation to the airport, not you. Again, he knows the costs involved, if he doesn't want to take it on, then he can politely decline.
Reply:I think if you were taking a vacation together you would split things; he pays for himself, you pay for yourself. But if he's just paying for the wedding, he'll essentially be making a big trip out there, essentially as a favor to you: I would offer to pay at least his hotel, if not both hotel and airfare. But if you're staying and he wants to leave but was invited, I wouldn't feel responsible for his transportation back to the airport; that's his choice, and if he stays for the wedding there should be ''someone'' heading to the airport afterwards.
