Does the flight booking API let me see what baggage allowance and seat selection options come with each fare?

Yes, the flight booking API can show you baggage allowance and seat selection details for each fare option, though what information is available depends on what the airline provides through the system. Most airlines include this data so you know exactly what your customer is getting when they book a particular ticket. Some airlines are more detailed than others about what they share, so you may see full information for one airline and less detail for another on the same route.

You can use this information to help your customers make better choices and to set expectations before they commit to a booking. If a customer is choosing between two fares and one includes a checked bag while the other does not, you can point that out and explain the real difference in value. This helps you provide better advice and reduces the chance that your customer gets an unpleasant surprise after they book.

Keep in mind that ancillary details like baggage and seats can change if an airline updates its policies, and the API will reflect those changes. You should check what specific details your flight booking API is configured to return, since each setup can be different depending on your contract with the suppliers and how your API is built. Contact your provider to see exactly which baggage and seat details are available in your system so you know what information you can show your customers.
