Departure in four hours: the hardest payment in aviation

A first-time customer calls at two in the afternoon for a five-figure flight departing at six. Every individual element of that is a risk signal, and they have all arrived together.

It is also completely normal business in charter, which is the tension. The controls that would make this safe are the controls that would lose the booking.

What fires, all at once

• ·New payer with no history on the account.
• ·Large ticket relative to the merchant's average.
• ·Card-not-present, with the cardholder frequently not the passenger.
• ·Near-zero gap between payment and delivery, so there is no time to verify anything after the fact.

What can be decided in advance

The operators who handle this well decided their escalation rules before the phone rang. Above a threshold, a second verification step happens regardless of urgency. A cardholder who is not traveling signs an authorization. Above a higher threshold, it goes to wire and the aircraft does not move until funds are confirmed.

Deciding that at two in the afternoon with a customer waiting is how operators end up carrying a fraudulent five-figure charge. Deciding it in advance makes it policy rather than a judgment call under pressure.

The fastest way to lose a last-minute booking is a decline at four o'clock. The most expensive way to keep one is approving something nobody verified.
