The Atlanta Business Chronicle reports that Delta Air Lines "will soon debut the first of 57 Airbus A319s that will receive a nose-to-tail interior modification." The updates include new Panasonic in-flight entertainment systems as well as larger overhead bins. Delta says, "All 126 A320 and A319 aircraft will be retrofitted with the new interior by summer 2017."
I think the new modifications look great! I love the LED backlighting around the new passenger service units. Since Delta obtained their A319/A320 aircraft after merging with Northwest Airlines, I have come to really enjoy flying on these aircraft and I look forward to experiencing the new interiors!
