Two years after I saved a woman’s life at 35,000 feet, I was at my lowest, struggling to make ends meet and reeling from my mother’s loss. On Christmas Eve, a knock on my door brought an unexpected gift and a chance at a new beginning from a stranger I thought I’d never see again.

I’d seen every kind of passenger imaginable in my years as a flight attendant — the nervous first-timers, the seasoned business travelers, and the excited vacation-goers.

But there’s one passenger I’ll never forget. Not because of her designer clothes or business-class ticket, but because of what happened at 35,000 feet that day. Two years later, she changed my life in ways I never could have imagined.
