Can I use the flight booking API to see what ancillary services like seat selection and baggage are included with each fare so I know what to tell my customers they're getting?

Yes, the flight booking API includes information about what comes with each fare, and you can pass that information on to your customers before they book. When you search for flights through the API, you get back details about included baggage allowance, carry-on limits, seat selection options, meal services, and other add-ons that vary by airline and fare type. This means you can show your customers exactly what they are paying for instead of them finding out after they book that they have to pay extra for a seat or checked luggage.

How much detail you see depends on what the airline supplies through the API. Some airlines share comprehensive information about every service and restriction tied to each fare, while others provide less detail. You will always get the essentials like baggage and seat selection, but extras like lounge access or priority boarding may not always come through. Your system will show you what is available from each supplier, so you can see what you have to work with.

You can display this information in your white label portal or share it with customers through your own booking process, so they make an informed choice before they commit. Some travel agencies use this data to highlight which fares offer the best value for money, while others use it to upsell premium fares that come with extra services. Check what your current API connection is returning in test searches so you know exactly what ancillary details you have available to show your customers.
