Airline tickets

It's been one of those typical crazy days of dealing with the airline and it is all in who you talk to!!  I called Delta earlier and was told that even though we had the adoption fare which was to waive all change fees & difference in fare, the discount tickets weren't available on Thursday. The woman at Delta said the change fee was $670 per ticket (x3) and so I opted to think about it and call back. I checked other airlines and it was pretty much across the board over $1000 to book a new ticket since it is only 6 days away.

I knew what I was up against as the initial booking of our special international adoption fare tickets took 7 hours on the phone and changing my ticket out of Bogota took hours. I prepared myself tonight with a little bit of alcohol!  ;)

I called Delta and was told by the customer service rep that it would be $900 per ticket to change their tickets from tomorrow to Thursday ($2700 total). I argued that a one way ticket is $913 so how could it be $900? Don't they apply the ticket we already purchased towards that amount? What about the rules of our fare which are no change fees? No difference in fare fees? What about the fact that when we had to change my return flight they figured it out and didn't charge me? I was put on hold for about 20 minutes and then she came back with "I am sorry but what I told you seems to be correct after consulting with out global fare department". I asked to speak to a supervisor who came on the phone after about a 5-8 minute hold. I talked for what felt like at least 10 minutes, then apologized for making my plea so lengthy. He asked "what date did you need?" and I replied with "Thursday". He simply said "OK, you are good for Thursday". I think I thanked him 3 times but he couldn't possibly have any idea how much that actually meant to me after a week of feeling so defeated and so unsuccessful. I wish I could send him a thank you card!!!
