St. Thomas right? Just checking since STT showed up as a VOR for the USVI. Ah, just checked DL
's site and that is the location.
If you do indeed get the 757 you will get a plenty wide seat (about 21" or so) and perhaps a footrest though I've never found those incredibly useful. I looked online and you should not get one of the ex-Song 757s since it is only showing 6 rows in F. You'll miss out on the AVOD but there will be the normal 6 month old movie on the overhead screens if you care to watch.
Once on board they'll offer you a drink but I doubt warm nuts since you aren't getting the full BusinessElite service. Of course the drink is served in a plastic cup but you'll be ok unless you are high falooting. After takeoff and before meal service you will be given a nice hot towel to wash your hands and face.
Given the pattern of what I have had in DL
F class over the past year for meals you're going to get either a grilled chicken breast with grilled veggies or a mushroom ravioli with a grilled chicken breast on top. There is no choice in Domestic F so you get one or the other. Perhaps since you're on a pseudo-international flight you might get a choice. The ravioli is pretty good. All the meals come with a roll, salad, and some sort of dessert concoction.
The stewardesses will keep your drink filled the entire flight and will be friendly with good Southern hospitality. I would guess that you will get a snack service of whatever you want from the basket plus more drinks. Take all you want but don't be a huge hog about it. They usually bring it around a couple of times before landing.
Other than that you'll get good service with a smile and hopefully on to your destination on time. Have fun and enjoy the islands. Search on my username (sorry too lazy to look them up right now) for a trip report going to the Bay Area. It's of the ex-Song 757 but you'll get an idea. Try the one for my first trip to Oz earlier this year as well. It has a 737 both ways from ATL
but again the stuff there will give you a good idea of what to expect.
