Brian Kelly, founder of the Points Guy, has made a career out of helping people travel using credit-card points and frequent-flyer miles. His readers have taken trips across the globe, flown first class, and stayed in five-star hotels — all using rewards. Kelly is out now with a new book, How to Win at Travel, which details travel advice that goes beyond points and miles. He spoke with Apple News In Conversation host Shumita Basu about ways to make your next trip easier and more affordable.
