I only remember a few. The food court menu is now slightly different (see Deb Wills site for the most current). Also, what I think is an improvement, is that you now go to the individual stations, get what you want, then pay for it, like at POR, instead of the former way, where you placed your order and paid first.
And if you remember the Sax player in the lounge, Elliot Dyson, he's not there, but the CMs told me they really want him back, so it's still possible in the future.
