Hi all,
Below is the reply I got from Fiji when I e-mailed them regarding the posting of miles a few days ago. It looks like they are still going to honor the skymiles offer for all (irregardless of the use of a coupon).
"We apologize for the inconvenience, but because this is our first launch of a promo such as this it will take a little longer then 3 weeks. We are in fact honoring the Delta Sky Miles so please be patient with us. I don’t have an estimated time, but I do know that we are working on the processing of these miles."
Hope this helps put some concerns people may have had!
