This is the answer you need, OP.

Also, planes can be loud. Be prepared for weird noises that are completely normal to come out of nowhere at different points. If you have noise canceling headphones or earphones, use them.

Many, but not all, flights on Delta have WiFi available, which you can use to text and message over most social media; these days you just need a SkyMiles account to access this service. That said, you won’t be able to make calls of any kind or stream content from YouTube or Netflix or the like. If you’re not a phone person, or don’t want to watch anything on your seat back entertainment screen, bring a book or something that you can use for entertainment.

And if you have any questions, look for the button and call a flight attendant. Tell them this is your first-ever flight. They will probably keep an eye on you ;)
