I believe you should have a good chance of getting a refurbished aircraft, with new IFE, seats etc.

Bad news is they're squeezing in an extra seat in every economy row, so instead of 3-3-3 it'll be 3-4-3 so you'll have less seat width.

So you can tell if you are on a refurb by checking the economy seat map to see if it's 9 or 10 abreast.
