American Airlines is touting a new app-and-website feature that can automatically book you a “free” hotel when an overnight delay strands you. The demo in its own promo is the perfect reminder of the catch: the airline room you’re offered is often the cheapest option available, not the one you’d choose to sleep in.
If you can front the cost, you can usually do better—using trip-delay coverage, distressed passenger rates, or points—without spending an hour in a voucher line.
