What is the best way to convert my AMEX delta card to the blue card without having to apply for the blue card?
The Delta won't convert to Blue as it is in a different product line. I believe you'll have to contact the MORE dept. and ask to transfer part of your Delta's CL to a Blue account....that might work.
True. You'd probably have to apply for a Delta after all, and - if declined - call MORE to move your credit line from the Blue to the Delta. Saar
