Thanks. That's what we intend to do. Delta Global Agency Support has said they've documented the record and all receipts have been kept.
I was more curious if anyone else had issues with DL codeshares operated by Transavia.
It's not exclusive to Skyteam.
As I mentioned, I sent her to the only true Skyteam office at Malaga that wasn't operated by a 3rd party (not that it should matter) and of course they could not/would not help.
I find it universal between OW/ST/SA that they are eager to sell but are incredibly resistant to help out when their is a problem with each others tickets.
