Advice | Miss Manners: Should I accept offered seat swaps when I’m flying for free?

Dear Miss Manners: I am privileged to receive free air travel benefits from my husband’s job as an airline pilot. My family flies on standby status, so we are usually among the last passengers to board the plane. Because of this, I am often separated from my 10-year-old. This is fine with us, as my son is an experienced traveler and is a quiet, self-sufficient and polite passenger.
