What do you get in premium economy on Vietnam Airlines?

Okay, but seriously, what do you get with Premium Economy on Vietnam Airlines? I'm thinking about splurging, you know? Long flights…ugh. So, it seems like you get quite a bit more space, which, hello, yes please! I'm picturing myself on a 12-hour flight (like that one time I flew to Seoul – never again in economy!), and that extra legroom? Life-saver. Seriously, a life-saver.

And the amenities! I can almost feel myself sinking into the seat, noise-canceling headphones on (are those included? I hope so!), lost in a book, or maybe catching a movie. Oh, and a charged phone! Because who wants to arrive with a dead battery? Talk about starting a trip off wrong.

One thing I am wondering though… they mention different aircraft having different seats. Hmmm. That makes me a little nervous. Like, what if I end up on the one with the less comfy premium economy seats? Anyone know which planes have the best ones? It'd be a bummer to pay extra and then…well, you know. Not get the really good experience. Maybe I should look into that before I book.
