Will I be able to see how much luggage is included in a flight fare, and can my customer buy an extra bag when they book?

Yes, in most cases the baggage allowance comes back with the fare before your customer pays, and extra bags can often be added at the time of booking. The flight booking API returns the cabin and checked baggage that belongs to each fare, so your portal can show it right next to the price instead of leaving your customer to find out later.

How much detail you get depends on the airline and on the supplier the fare came from. Full service airlines usually pass a clear allowance, such as a number of pieces or a weight in kilos, and that displays cleanly. Low cost carriers often sell baggage separately, so the fare arrives with little or no allowance and a list of bags you can add for a fee. A few airlines only confirm the allowance at ticketing, and in that case the honest thing is to show what the API gave you and tell your customer to check their ticket.

Adding an extra bag through the API works wherever the airline supports it. When it does, the bag is attached to the booking and paid for along with the ticket, so there is nothing for your customer to settle at the airport counter. Where the airline does not support it, they will have to add the bag on the airline website or at check in, and it is better for your portal to say so plainly than to stay silent about it.

Check with us which of your airlines and suppliers return full baggage details, and decide how you want your portal to word an allowance when the airline has not given one.
