It's important to remember that by posting here you're not writing to Delta, you're writing to a bunch of loyal Delta customers. We can't do anything about your complaints, and we're the most likely people to be offended by them. Maybe the OP knows that and is trolling us, but if not, here’s what you need to know:

With the exception of the 717 and the few remaining unmodded A320s, almost the entire modern mainline Delta fleet has personal TVs at every seat. That is not true on any other major airline, Delta really excels in this area. Delta is also currently installing satellite wifi on its aircraft that works over the oceans, which is also not true of any other major airline. Most planes use ATG wifi which only works over ground. As for the service, it can be hit or miss. I like to think it’s better more often than it isn’t.

If Delta got you from point A to point B in the class of service you paid for, then they did their job perfectly. Next time you’ll probably end up on a freshly modded plane and will enjoy your experience a bit more.
