The brief

A vendor (simulated) offers a 90-day trial of a no-show prediction service for the synthetic airline and asks for 24 months of passenger-level booking records so it can "train a custom model". The airline operates 19 flights a day (6,935 departures a year, as in the course database) and about 1.1 million bookings a year (1.07 to 1.13 million in the course database). You currently use an in-house logistic model. All people, opinions, fees and values are simulated or hypothetical; the passenger data is fictional.

Colleagues involved: a product manager who wants the trial in four weeks; a privacy and legal reviewer; a security lead; a data engineer; a finance partner; and the commercial director.

Stage 1 of 4

The vendor's request lists these fields per booking: name, e-mail, phone, passport number, payment token, IP address, booking key, fare class, days to departure, party size, sales channel, route, exact departure date, and the no-show outcome for every booking.

Which items may go in the first release to the vendor? Select all that apply.

A random booking key (mapping kept by us), fare class, days to departure, party size, sales channel and training-period no-show labels.Route, departure weekday and month, with exact departure dates withheld until the evaluation window.Names, e-mail addresses and phone numbers, so that the vendor can recognise repeat travellers across bookings.Passport numbers and payment tokens, which the vendor says improve its identity matching and fraud screening.The no-show outcome for the last three months as well, so the vendor can tune its model before the trial ends.
