Almost everything changed regarding winter charter flights to Salzburg in the last decade. TUI Airways for example operates frequently with its new Boeing 737-8 MAX. But the moles still love the soil around the runways :-)
Beginning with the 7th aircraft in Malta Air fleet (from the letter G up) the B737-8 MAX 200 aircraft unfortunately started to get classic Ryanair colours. So sometimes both versions of colour scheme meet at the same time at Bratislava on flights from Milan-Bergamo and Bologna.
