FREQUENT FLYER GLOSSARY
What is a mixed-cabin award?
A mixed-cabin award is a single award booking in which the traveller sits in one cabin on part of the journey and a different cabin on another part — lie-flat business class on the long-haul sector and economy on the short connection, for example. Whether such an itinerary can be booked at all, and whether it is priced at one cabin or flight by flight, follows the programme's own award rules; American Airlines, for instance, does not offer its cash-and-miles booking for reservations that include travel in different cabins. [1]

Key takeaways
- A mixed-cabin award is an itinerary question rather than a separate award product: the booking covers two or more flight segments, and the cabin changes somewhere along the route.
- The rules that decide whether the cabins can be combined, and what the whole itinerary costs, belong to the programme being used, so they need to be read programme by programme rather than assumed.
- American Airlines excludes reservations that include travel in different cabins from cash-and-miles bookings, along with trips that include another airline, international flights and multi-city bookings. [1]
- Qantas treats each change of flight number as a new flight, even where there is no change of aircraft, so a connecting journey is built from separately identified flights. [4]
Why do mixed-cabin itineraries come up?
A journey of any length is assembled from flight segments, and the cabins on offer can differ from one segment to the next. Short feeder flights often use smaller aircraft with a single cabin, while the long-haul sector they connect to may have a premium cabin. Award availability can also differ by cabin on each sector, so a traveller may find a premium seat on the long flight and only economy on the connection.
The vocabulary matters because programmes define the pieces of a journey themselves. Qantas defines a “Flight” as one-way travel on a scheduled air service with a single flight number, and provides that where travel includes a change of flight number, each change is a new Flight even if there is no change of aircraft. [4] A “Segment” is the portion of a journey between two consecutive points listed on an itinerary, and a “Flight Segment” is a segment that has been or is intended to be flown. [4] Qantas also defines a “Trip” as consecutive flight segments that contain no stopover, stay within the maximum permitted miles in the applicable Classic Flight Reward table, and are not broken by a change to or from any airline in its partner Classic Flight Reward table. [4]
How is a mixed-cabin itinerary priced?
Three broad approaches exist, and the programme's award rules say which one applies. The itinerary can be priced as a whole at the highest cabin used, so that a cheap short hop does not lower the cost of the premium long-haul sector. It can be priced segment by segment, so that each flight carries its own cabin rate. Or the journey can be split into two separate awards, one per cabin, each with its own availability and its own change and cancellation terms.
Programme pages set out these arrangements to different degrees. Cathay's membership terms, which took effect on 1 January 2026 (Hong Kong Time), deal with “Miles Plus Cash” and with oneworld multi-carrier flight awards in separate sections. [3] Qantas treats an upgrade as its own reward: a Classic Upgrade Reward is the redemption of Qantas Points for travel in a higher cabin class than the class of the fare tendered. [4] Qantas also says points and status credits are earned for the class originally purchased or redeemed rather than the upgraded class. [4] On the American side, partner airline flights appear in award search results and can be filtered by airline on the “Choose flights” screen, so the carrier behind each segment is visible before booking. [1]
What do programmes publish about cabins and carriers?
| Programme | Rule as published | What it governs |
|---|---|---|
| American Airlines (AAdvantage) | Cash and miles isn’t available for reservations that include travel in different cabins [1] | Cash-and-miles bookings made on aa.com or in the American app [1] |
| American Airlines (AAdvantage) | Cash and miles isn’t available for trips that include another airline, international flights or multi-city bookings [1] | The same cash-and-miles bookings [1] |
| Singapore Airlines (KrisFlyer) | Miles cannot be used to pay for a fare that includes a flight segment not operated by Singapore Airlines, such as a codeshare, an interline itinerary or a round-the-world itinerary [2] | Using KrisFlyer miles to offset the price of an airfare [2] |
| Qantas (Qantas Frequent Flyer) | A “Trip” of consecutive segments must not be broken by a change to or from any airline in the partner Classic Flight Reward table [4] | The Trip definition used for Classic Flight Rewards [4] |
| Cathay (Cathay Membership Programme) | “Miles Plus Cash” and oneworld multi-carrier flight awards appear in separate sections of the membership terms, which took effect on 1 January 2026 (Hong Kong Time) [3] | Cathay membership terms governing redemptions [3] |
Reading a rule correctly means checking which kind of redemption it governs. American lists the cabin exclusion among the conditions of its cash-and-miles booking, which is available only on flights marketed and operated by American within the contiguous 48 U.S. states. [1] Singapore Airlines draws a similar boundary for a different purpose, barring KrisFlyer miles from being used against a fare that includes a segment it does not operate, giving codeshares, interline itineraries and round-the-world itineraries as examples. [2]
Exceptions and limits
- American cash-and-miles exclusions. Cash and miles is also unavailable for Basic Economy fares, flights to, from or within Alaska or Hawaii, international flights, multi-city bookings, trips that include another airline, AAdvantage Business bookings and TripLink bookings. [1] Booking requires AAdvantage membership, a valid U.S. home address saved in the AAdvantage profile and at least 500 AAdvantage miles. [1] Cash-and-miles bookings are not eligible for voluntary changes or exchanges, so a change has to be handled by cancelling and making a new reservation. [1]
- American award tickets paid in miles. There are no change fees for award tickets, although a fare difference may still be payable, and miles are reinstated to the original AAdvantage account. [1] Cancellations are free up to one year from the date the ticket was purchased, as long as the trip is cancelled before the first flight departs. [1]
- KrisFlyer payment limits. KrisFlyer miles cannot be used to redeem for tickets bought through travel agents, Singapore Airlines ticket offices or call centres, or Scoot ticket offices or call centres, and cannot be used to pay corporate fares, group fares or fares including a segment not operated by Singapore Airlines. [2] Tickets redeemed fully or partially with KrisFlyer miles are non-endorsable, regardless of the fare conditions. [2]
- Availability. Qantas states that Reward availability is limited. [4] Singapore Airlines reserves the right to modify award structure, award levels and the availability of awards without prior notice. [2]
- Changing a Qantas Reward. A change requires any additional Qantas Points or money needed for the new booking, a Change Fee, and any additional taxes, fees and carrier charges. [4]
Frequently asked questions
Can a single award booking cover two different cabins?
That depends on the programme and on the type of redemption being made, so the cabin mix has to be checked against the rules of the programme being used. American Airlines, for example, excludes reservations that include travel in different cabins from its cash-and-miles bookings. [1]
Does American Airlines allow cash and miles on an itinerary with different cabins?
No. American lists reservations that include travel in different cabins among the bookings for which cash and miles is not available. [1]
What counts as a flight segment on an award itinerary?
Qantas defines a Segment as the portion of a journey between two consecutive points listed on an itinerary, and a Flight Segment as a segment that has been or is intended to be flown. [4] Its terms also provide that each change of flight number is a new Flight, even without a change of aircraft. [4]
Can KrisFlyer miles pay for an itinerary that includes a codeshare or interline segment?
Not where the fare includes a flight segment that is not operated by Singapore Airlines; the terms give codeshares, interline itineraries and round-the-world itineraries as examples. [2]
Are award tickets paid with KrisFlyer miles endorsable?
No. Tickets redeemed fully or partially with KrisFlyer miles are non-endorsable, regardless of the fare conditions. [2]
