I used their email function (thru "voice a complaint")--and that worked quite well. Got a response within a day, and it is mostly worked out (we were supposed to be in the PNW last week). Only issue is a refund for the flight (right now we have credit) but they said they are working on it as my original flight was cancelled and the replacement (three legs vs two) was more than 90 minutes from the original time, which counts as an eligible flight fro a refund. All things considered, I was pleased with my interaction with Delta.We were going to Europe for a couple of weeks in June. We have cancelled that unfortunately. I guess we spend more time at our other house and do some days at Raystown lake. Thinking about doing a beach trip to Isle of Palms maybe in later summer.
Here's a travel tip for everyone. Delta cancelled our flights to Europe and didn't advise us. I tried to call them to ensure our miles got redeposited and our cash fees refunded. The hold time was 6 1/2 hours! LOL. So I tweeted at Delta saying you cancelled, didn't tell me and haven't refunded or redeposited anything. Within 10 mins, I got a Twitter DM from Delta and they resolved it within an hour. I will remember that for future issues when I can't reach them in a conventional manner.
