Air Canada has released a retro livery on their newest A220 registered C-GNBN in the Trans Canada Air (TCA) livery. I think they did a stunning job here. The airline on its Twitter said
Fresh from the Airbus paint shop in Mirabel, our brand new A220-300 proudly recognizes our heritage with a special Trans-Canada Air Lines (TCA) livery. It will soon join our fleet in the sky, stay tuned!
Take a look!
