i did something stupid, and now i'm not sure what to do.

i serve on a committee for an international professional association.  a couple of times a year we meet to hash out professional-association stuff.  it is an unpaid position, though it's an honor to be on the committee. 

i don't get paid for the work days i miss, so i lose money being on the committee.  but i enjoy it, it's great to spend time with some of the brightest minds in our field and it's a change from my daily routine. while we're there, they pay our expenses, hotel, evening entertainment (quality things like box seats to mlb game, dinner and a show, etc.).  we purchase our flights and submit for reimbursement our out of pocket expenses. and this is where i'm a dumbass.

we are supposed to arrive thursday and stay in the hotel and work starts first thing friday morning.  i just made a mistake, and booked my flight for wednesday.  i sent the flight info to the society, and they emailed me that i was supposed to be coming in on thursday.

so i called the airline.  my original flight round trip was $315.  to reschedule, the "change fee" is $200 and the new seat on thursday is $150.  so i already paid $315 for the first itinerary and now i've paid another $350 to get in on the right day.  i spoke to the coordinator and we agreed we'd hash out the reimbursement on this trainwreck.

so today i emailed the coordinator, and asked what she wants to do about the rescheduling of the flight, and how i should handle submitting for the expense.  in the email i again acknowledge that it was my mistake.  her reply:  "i'm leaving that up to you."

so, what would you do?  put in for $315, $350, or $665?  my wife won't be happy with having to eat several hundred because i'm a dumbass, especially since my attending costs the household money.  but it doesn't seem right sticking them with the full cost of both bookings.  what to do?

TIFU by booking the wrong airline flight, generating unnecessary expenses. Opinions on how to handle it.
