Hello family of 4 flying from Phx-Vancouver via Seattle Sunday for cruise. I don't travel much and really don't like flying. I was not aware this was a small aircraft. Why is an aircraft this size being used on a 3 hr flight? Is this normal? Only holds about 80 people. This will be my sons first flight he is 6. I have the Xanax ready but wished I would have paid more to get a bigger jet. Any words of wisdom is appreciated.
