Parse and display baggage allowance information from an Amadeus flight offer

Steps

1. After retrieving a flight offer from the Amadeus Flight Offers Search API, locate the pricingOptions and travelerPricings arrays within each offer object.
2. Within each travelerPricing, inspect the fareDetailsBySegment array; each entry contains an includedCheckedBags object with quantity (integer, number of bags) or weight (integer) and weightUnit fields.
3. If the includedCheckedBags quantity is 0, the fare is typically carry-on only; surface this prominently as baggage fees may apply at check-in.
4. For chargeable extra bags, note that additionalServices.chargeableCheckedBags uses the same BaggageAllowance shape but represents a paid add-on, not an included allowance — do not merge the two when displaying totals.
5. When displaying allowances, group by segment because long-haul and short-haul legs within the same booking may have different baggage rules.
6. To get the most accurate baggage data, re-confirm allowances via the flight offers pricing endpoint before order creation, as allowances can differ from initial search results.
