I'm a total newb to the whole drink coupon aspect of flying. I've got a few Delta trips coming up and I was considering buying some drink coupons on eBay for them. I've got a few dumb newbie questions. First, has anyone ever had any issues doing this? They're not going to care that I bought them online? Can I use more than one per flight? If I want more than one drink, will I be able to get them with the coupons? What kind of cocktails can you get with them? Is there a list anywhere online of Delta's in flight drink menu?
