Brand new Diamond! Global/Regional upgrades Ver 3.1
Greetings. I seem to be getting conflicting information on using my Global Upgrades.
Looking for 2 Global Upgrades to business, CDG-DFW on Air France, (wife's preference) or KLM on either September 17,18, 19. and DFW-CDG either December 17,18,19. We will use DL if necessary. both directions.
1. What class of Service/fare code should we buy to get upgraded to business on AF/KLM?
2. Should I call Delta (again)? 3 agents didn't seem to know much about GU's. Or should I call AF or KLM directly?
3 Are there any other questions I should be asking?
4. Any suggestions?
Thanks in advance for any and all help!
