The A321neos don’t have DL Sync yet. Just flew on one last week in FC. Bluetooth headphone con connectivity is nice but the lack of pre-ordering is getting annoying especially with inconsistent FAs following FEBO. My last Neo flight on an odd # flight, the FA started to take orders with Row 1, then quickly likely realized it was an odd # flight and went straight back to row 5. By the time they had gotten to Row 4 (which was basically Row 3 when it came to taking meals) the FA told me they just ran out of the Short Rib. They apologized and said the Neo has limited oven space for hot meals. DL needs to fix this ASAP especially since the Neo almost exclusively does meal length flights.
