Succubus Vs. Airbus

I like flying but after this trip my brain plainly fused as I got off the plane and the question 'What is the difference between a Succubus and an Airbus?' popped into it. Both interrupt your sleep, suck out your vitality and, in short, age and wither you. The differences are that Succubi generally involve sex in some way which despte many tacky illusions does not happen much on planes, that and the fact that you don't get a small tasteless meal from a Succubus every three hours.
