The playbook
Booking a mistake, without making one.
Book first, plan later
Error fares survive minutes to hours. Book directly with the airline when possible, then decide if you’re actually going.
No side bets for 1–2 weeks
Hotels, connecting flights, time off — nothing non-refundable until the ticket is confirmed and past the airline’s cancellation window.
Wait for the ticket number
A confirmation email is a handshake. A 13-digit e-ticket number is a contract.
If cancelled, escalate politely
A full refund is the floor; documented out-of-pocket costs are usually reimbursable on US departures.
