How alliances and partner awards work
Airlines in an alliance generally honour each other’s awards, so miles in one program can often book seats on another member’s flights. That is genuinely useful — it is how bank points with no direct route to an airline can still get you onto it. But two things trip people up: an alliance badge tells you nothing about whether your points can reach a given program, and airlines release a smaller, more restricted set of seats to partners than they sell their own members.
The three alliances
Star Alliance, oneworld and SkyTeam are the three global groupings. Membership means member airlines will generally let each other's members book award seats on their flights, subject to each program's own pricing and rules.
Plenty of airlines sit outside all three and run bilateral partnerships instead. Those can be generous, but they have to be checked airline by airline — there is no badge that tells you they exist.
Why partner award space is different
An airline decides how much of its award inventory to release to partner programs, and it is typically less than it makes available to its own members. So a seat you can see on the operating airline's own website may simply not be bookable with partner miles, at any price.
This is the single most misunderstood thing about partner awards. Seeing the seat is not the same as being able to book it with the miles you hold. You have to search from inside the program you would book with.
What an alliance badge does not tell you
It does not tell you your points can get there. Whether Amex, Chase or any other currency reaches a given program depends on that bank's partner list, which has nothing to do with the airlines' relationships with each other.
Our path finder deliberately refuses to infer a route from shared alliance membership. If we have not verified a path, it says so rather than guessing — because a guess here leads to an irreversible transfer.
How a partner booking actually goes
The typical shape: your bank does not transfer to the airline you want to fly, but it does transfer to a program that can book that airline's partner award space. You search from inside the partner program, find the seat, transfer, and book there.
Pricing follows the program you book with, not the airline operating the flight. That is often the whole point — one program's chart may price a route far more cheaply than the operating airline charges its own members.
The mistake: assuming the alliance is enough
"They're both Star Alliance, so my points will work" is the reasoning, and it fails in two independent ways. Your points may not reach any Star Alliance program at all. And even if they do, the specific seat you want may not be released to partners.
Both failures are only discovered after an irreversible transfer, which is why we treat this as the headline warning rather than a footnote.

Questions people ask
Can I always book any alliance member with any member's miles?
No. Alliance membership makes it generally possible, but each program sets its own rules, prices and partner access, and some pairings are restricted.
Why is the partner price different from the airline's own price?
Because the program you book with sets the price, using its own chart or pricing model. That is why booking through a partner is sometimes considerably cheaper than booking with the operating airline's own miles.
Where do I search for partner space?
Inside the program you intend to book with. Searching the operating airline's own site shows you what it sells its own members, which is a different and usually larger pool.
