If you're talking about DUB-CLT on 8/1, that's being operated by N780AN and tonight it's going CLT-DUB. The flight search shows a wifi symbol. It doesn't show up when I search DUB-CLT on 8/1, likely because it's sold out.
That being said, I've learned not to rely on satellite wifi over the ocean too heavily. It can be slow at times and spotty coverage.
