Forgetting a passport or ID is a stressful mistake, but not always the end of your trip.
If home is close, ask for the next available flight the same day. Standby may also be possible.
A paid change is often cheaper than buying a new ticket. Ask for the exact fee before you decide.
On non-refundable tickets, the base fare is often lost, but unused taxes and fees can often be refunded if you ask in writing.
Forgetting documents is often excluded, but check your policy and credit card benefits.
Tell the airline you still plan to travel.
Keep documents in one pouch and check them the night before.
