It’s among the worst feelings in the world. You’re running across the terminal when you hear that announcement that your “gate is now closing” and you know you won’t make it there in time. Or, just as bad, you’re stuck in the air circling the airport as the plane of your connecting flight takes off without you.
Missing a flight can add layers of trouble and delays to your schedule. But if you can keep a level head, in most cases you should be able to board a suitable alternative flight and start heading in the right direction ASAP.
