Airline tickets, upgrades, mileage points purchases, mileage points transfer
fees, gift cards, duty free purchases, and award tickets are not deemed to
be incidental fees. The airline must submit the charge under the appropriate
merchant code, industry code, or required service or product identifier for
the charge to be recognized as an incidental air travel fee.
除了这两个 checked bags and in-flight refreshments
这么看， 还有哪些能算在incidental fees呢？
谢谢
