Planes are too dangerous.
What if your plane is hijacked and 7/11 is caused
Or it crashes sometimes
On the contrary, there are less fatal plane crashes per year than savage vending machine killings.
You have to understand that most "incidents" are minor at best; for example, a pilot requiring a touch-and-go because he's overshot the runway, or a bird-strike into an engine. Even major incidents like a plane fire or a hijacking can result in 0 fatalities and a safe landing (not gonna link the specific accident reports, but trust me that both of these are true).
I consider Southwest better because Qantas has had a fatal crash a long long time ago.
QANTAS has had 6 fatal non-military incidents during operation previous to the late 1950s, but all were in non-modern aircraft, and several of those were due to design faults in the models of aircraft.
