I just posted this on FT, too, but there is a reservation agent taking all questions right now on Reddit. I don't fly Delta a lot but I thought milepointers might upgrade the Q&A discussion. Redditors are not typically frequent fliers, so the questions so far have been fairly mundane. "I am a Delta/KLM/AF reservation agent that knows all the tricks to booking low fares and award tickets. Ask me anything."
