They are using STN flight times and flight number instead of the usual NCL EK35/36 times
EK033/034 were the old STN flight numbers when the service launched single daily in 2018 as an afternoon arrival/evening departure, with a long layover inbetween.
When it went double daily from July 2019 the new flight numbers became EK065/066 and EK067/068. They're showing STN from March 2022 with just the afternoon EK065/066 rotation.
EK033/034 hasn't been used since, and the NCL winter timings are not the same as the previous STN times, which was a 17:45 arrival (EK067) and 20:15 departure (EK068).
