Wouldn't it be ironic, and of course tragic, if you did take separate flights and the two airplanes collided in mid-air?
And you do understand that by taking two separate flights, instead of one, you would double the likelihood that at least 1 of you would die a horrible death in an air crash.
I trust that you never order the same thing in a restaurant, just in case one of the dishes has instant-death poisoning in it.
Seriously, though, you must have read the Hotel New hampshire.
Have a Great Day!
