Update: This code no longer worksOne of the reasons why I fly Delta is because I can count on there being wifi on pretty much every flight - including regional jets. As a full-time blogger, I feel isolated without internet and I’m unusually productive in the air - probably because I don’t have the distractions of working from home or the road, including bothersome phone calls.While this deal does me no good because I just bought a $39.95 unlimited Gogo monthly package, Delta and Diet Coke are teaming up to offer free wifi for the month of August when you use code DIETCOKEGOGO.Update: I’m on a Delta flight right now and I can confirm the code works, though it only showed me an ad for the free code when I used my iPhone and not my laptopThanks Diet Coke!Hat tip TPG Twitter Follower @wigmuke.
