Can the software save my regular customers' passport and frequent flyer details so my staff don't have to type them in every time?

Yes, in most setups you can keep a saved profile for a regular customer and pull those details straight into a new booking instead of typing them out again.

A customer profile usually holds the things you repeat on every trip, such as the name exactly as it appears on the passport, date of birth, nationality, passport number and expiry date, contact details, loyalty or frequent flyer numbers, and simple preferences like a window seat or a special meal. When your staff start a booking for that customer, they pick the profile and the fields fill themselves, which cuts down on typing mistakes in names, the kind that are slow and expensive to correct later. Exactly which fields you get, and whether you can store more than one traveller under a single customer, depends on your plan and how your portal has been set up.

There are honest limits worth knowing. A saved frequent flyer number will only be attached to the ticket if the airline or supplier accepts it for that fare and route, and some suppliers simply pass seat or meal notes along as a request rather than a guarantee. Saved details also go stale, passports expire and people change phone numbers, so a stored profile should never replace a quick check against the real document at the time of booking. You are also holding personal data, so it should sit behind proper logins rather than in a shared spreadsheet.

Before you rely on it, ask which profile fields are available on your plan, decide which of your staff should be allowed to view stored passport details, and agree a simple habit of confirming passport expiry with the traveller on every new booking.
