My husband and I booked flights on 3.8.23 for our Anniversary/2nd Honeymoon. The particular international flight we chose was listed as a Delta/Air France collaboration, which we specifically looked for. When our itinerary came to my email, it only said Delta with no mention of Air France. We were going to try to upgrade it for the celebration, on the Air France international flight. After three separate calls and an utterly futile 32+ minute chat to customer service (both on 3.10.23) left us with little hope we'll actually fly on what we booked on Expedia.com (Air France/Delta) nor does an upgrade seem possible (I asked the chat agent for a price three times & got no answer). I have used Expedia for over 20 years, but after how much stress this experience has CAUSED rather than prevented, this well may be the end for me. We are exasperated and heartbroken!
