Flight strategy

There are three siblings, two of them are a taking a flight, one is staying home. Should the two siblings take the same flight together, risking the third sibling being alone should a flight tragedy occur, or should the two siblings take separate flights ensuring the third sibling is not left alone.

The one not flying is evidently old enough to stay home by himself. The rest seems like a bunch of noise.

If they take two different flights, then all 3 siblings will be "left alone" for a while, at least as long as the flight takes before the two are re-united.

Also, if they take two separate flights, then they double the chance of a sibling being in a flight accident. In that case, the sibling who died in the airplane would then be "left alone" because he'd be dead.....and if I'm interpreting what you're saying, we want to minimize the probability a sibling is left alone?

They should defiantly fly on separate plains.

Really? Fly together. The risk is way to small to even consider.

Besides, if they travel seperately, and one plane goes down, Survivor’s Guilt will consume the other sibling that flew.

Also, travel by automobile is far more dangerous / risky. Do the siblings ever travel by car together?

One flight. Two flights pretty much doubles the chance that one of them will be, er, "involved in a flight tragedy." It also introduces the possibility that one of them gets delayed, and, as a result, they are unnecessarily separated for an extended length of time.

I thought the same thing. FYI, for others if unclear, left alone means being the only one alive with no other close family. The odds are low you're right.

Travel together. This includes not only flights, but travel to and from the airport coming and going. The odds of a ground travel accident, with 8 exposures vs. 4 (riding together) more than make up for the miniscule chance that something will happen to the airplane both are on. Whatever that chance is (of catastrophic airplane flight), it is also doubled with separate flights.

I disagree, slightly.

Let's get morbid and say planes have a 90% probability of going down on any individual flight, even though it's nowhere near that:

One flight, both siblings: .1 * 2 = 0.2 Siblings Dead on Average

Two flights land safely: .81 * 0 = 0

One flight crashes, the other doesn't: (.9 * .1) + (.1 * .9) = .18, siblings dead, also .18

Both flights crash: (.1 * .1 * 2) = .02

TWO FLIGHTS, AVERAGE SIBLINGS DEAD: 0.2

So, the probability of at least one being involved in a crash increases with two flights, but the average number of siblings who die remains the same and the probability of both siblings dying (which seems the focal point of the OP) goes down relatively dramatically.

It doesn't double the chance that one of them will, though. It doubles the chance that AT LEAST one of them will.

If it is me and my oldest brother, one flight since he is fun

If it is my other brother, two flights because he is annoying

Everyone forgot one flight can be two takeoffs and two landings or more. I did. Kind of scary. I guess it could be argued if your plane crashes, you don't lose anything personally because it's pretty much lights out like a bad dream. Weird idea to think not many people are even conscious when they actually die.
