Many years ago my parents were flying from the British midlands to Raleigh, NC. At Christmas.

I told them. "Whatever you do, do not book a flight through Chicago."

They booked a flight through Chicago. Note I had been very clear.

"It was several hundred dollars cheaper."

I informed them "It was not worth it."

They were flying back on January 1.

The year was 1999. Look it up.

Do Not Fly Through Chicago In Winter.

Ever.

No matter HOW much cheaper it is.
