I actually wondered the same thing before my first long Delta flight overseas. I remember stressing about whether my phone and laptop would survive the whole trip since I had some work to finish and didn’t want to land with a dead battery. Before flying, I tried searching online and got mixed answers—some people said every seat had outlets, others said it depended on the plane. So, when I boarded my Delta flight from Atlanta to London, I made it a point to check for myself.
To my relief, there were charging outlets in economy, right under the seats. They weren’t super obvious at first, and I had to lean down to find them, but once I plugged in my phone, it started charging immediately. I also noticed a USB port on the seatback screen, which came in handy for my earbuds and small devices. I’ve been on a couple of Delta international flights since then, and while most of them had outlets, one older plane didn’t, so I learned to always bring a portable charger just in case.
Overall, Delta’s pretty good about providing outlets in economy, especially on their newer international aircraft. If you’re flying soon, I’d say double-check your plane type when you book—mine had them, and it definitely made the trip more comfortable.
