I booked a trip with a travel agent. The TA then negotiated the actual private tour with a tour company in the country we are traveling to. The itinerary that we confirmed stated that the flight returned to the US at 5:05pm on Tuesday. It turns out that I just looked at the issued tickets and we arrive at 5:05 am on Wednesday. Unfortunately, my husband must be at work for a court trial 9am on Wednesday. I have everything in writing that states in the itinerary that we are returning on Wednesday. Of course, the change in tickets is about $1400 and the extra hotel night with private guide is $650. I paid using a combo of check and credit card. Correct me if I am wrong, but aren't they obligated to correct this mistake?

Oops! I meant TUESDAY! Nothing in the itinerary says WEDNESDAY!

What did the TA say when you brought the error to her/his attention?

Where are you traveling?
Are you crossing the Int'l Dateline?
If so, this may be the cause of the error.

However, if the TA advised/confirmed that you're returning on Tuesday "pm" and the itinerary indicates Tuesday, the TA should be responsible for the error to next day in the "am". At minimum, for the change fee.

Please let us know how this gets resolved. If your husband is a lawyer, and that's why he must be in court, I'd include that fact when discussing the situation with the agent.

We actually left for vacation and before we took off, the TA said that she would pay the cost of changing the tickets so we return on Tuesday. She added that this was personally costing her $680. I emailed her back and thanked her for rectifying the situation and reminded her that we should be refunded the $600+_ for the night we cannot use. I told her that I would imagine that the tour company would refund the money given the situation. She said responded that she hoped they would and asked if we would apply the refund so she could pay the cost of the tickets. So essentially if we did, we would be paying to fix the mistake she made with no cost to her. That seems insane to me. So I wrote her back re-explaining that the tickets were issued before I ever saw them and that there was no way I could have prevented this from happening. I also added that my husband and I would be willing to split any refund we received from the tour company 50-50 with her as a courtesy. What do you guys think? If the tour company does not refund the money, what should I do about the lost $600+?

I think you are 100% right. And generous to split refund 50-50. However, Doctor, sometimes stuff happens and we just have to eat it. Will you miss $600 a year from now, Doctor?
