Actually, SunExpress Deutschland should have renewed the fleet with eleven Boeing 737 Max 9s. This will not happen, however, because shortly after the start of the corona pandemic, the liquidation of the former holiday airline was initiated.
A machine of this type in full paint from SunExpress Germany has been standing around in the USA since 2019. Due to the worldwide flight ban, the medium-haul jet, which should have had the D-ASMA registration, could not be delivered. No sooner was this canceled in Europe than Corona caused an even more far-reaching defacto-grounding.
For SunExpress Germany, the corona crisis brought the final blow, because the voluntary liquidation was decided. The workers have lost their jobs. The Turkish SunExpress is not affected by this measure. This is still active on the market.
What happens to that Boeing 737 Max 9 that is standing around in full livery and waiting for better times? This should now go to Alaska Airlines. For this purpose, the medium-haul jet was brought to the paint shop, where it was given the color dress of the actual customer. The current test registration of the affected machine is N1784B. By the way: Another Boeing 737 Max 9, which should have joined SunExpress Deutschland as D-ANSB, was also given the full livery of the former German airline.
The following slideshow shows some impressions of the Boeing 737 Max 9 in the livery of SunExpress Germany. As reported, however, these were never floated.
