An ultra-low fare passenger air carrier ie, Spirit or Swoop, it offers such no frills amenities as all-economy seats. They may or may not offer wi-fi, and if you get hungry or thirsty then you have to buy your overpriced chips and soda.
McAirlines are like McDonald’s, offering cheap stuff that serve their purpose to the widest customer base.
I flew with a McAirline from Toronto to Calgary early this morning. The seats were cramped together and I had to pay for my chips and Diet Coke, but I arrived in one piece. That’s good enough for me.
A private jet that is just a smaller version of an airliner. Similar to how a small mansion is called a McMansion.
That Dassault Falcon 10X is a McAirliner because it can seat up to 19 passengers.
