I wonder if/when DL is going to go back to the previous 'old' service in D1... meaning the initial beverage/nuts round, then appetizer course, then main meal on tray, then desert cart with various options desert wine and port offerings.

Currently it is still just the bev/nuts, then full meal on tray, then choice of desert (usually ice cream or a cake/tart). My recent international D1 flights have had the service be very/overly rushed. On CDG-BOS last week they did the beverage/nuts and immediately came with the meal so quickly that pax didn't even get more than a sip of their drink. Same with desert, it all was very hurried.

Food quality was quite good - had a delicious cod fish meal and nice wine - but was pretty surprised at the relatively low level of service and poor pace. It felt like I was on an overnight flight to EU with the dine & rest option.
