Does anyone know On shuttle flights, was it always a 1:1 exchange when crew changes were made on orbit? I.e. does shuttle passengers launched = shuttle passengers returned?
I can unfortunately think of a couple more
where passengers launched Does Not = shuttle passengers returned
(even if passengers launched = shuttle passengers attempted to be returned)
Atlantis - STS-129 was 6 crew members up and 7 down.

Atlantis - STS-129 was 6 crew members up and 7 down.
A related question is how many passengers have returned on a different type of spacecraft than they launched on:
Mir EO-18: Soyuz TM-21 up, STS-71 down.
Mir EO-19: STS-71 up, Soyuz TM-21 down.
ISS Expedition 1: Soyuz TM-31 up, STS-102 down.
ISS Expedition 6: STS-113 up, Soyuz TMA-1 down.
This happened when Shuttle was used for full crew exchange. The first crew in the series goes up in a Soyuz and comes back on Shuttle, and the last crew in the series does the reverse. In the meantime, short-duration missions go up to refresh the Soyuz lifeboat.
The other situation, where the launch crew was not the same size as the landing crew, happened when Shuttle was used for single-person crew exchange, where the first astronaut in the series goes up and stays, and the last astronaut in the series comes down and is not replaced. This happened for STS-76 and 91 on Mir, and STS-121 and 129 on ISS.
STS-71 and Soyuz TM-21 had different-sized up and down crews because Mir EO-18 and EO-19 were not the same size.
Numerous Soyuz flights were 2 up/3 down or 3 up/2 down, including Soyuz TM-2, TM-10, TM-15, TM-16, TM-17, TM-18, TM-19, TM-21, TM-23, TM-25, TM-26, and TM-28 to Mir, and Soyuz TMA-2, MS-03, and MS-04 to the ISS, due to extra-long missions, changes in the size of the long-duration crew, or whether a short-duration mission used the third seat.

What You Need to Know about NASA’s SpaceX Crew-6 Mission
A new set of four crew members are preparing to launch to the International Space Station as part of NASA’s SpaceX Crew-6 mission.
NASA astronauts Stephen Bowen and Warren "Woody" Hoburg, as well as UAE (United Arab Emirates) astronaut Sultan Alneyadi, and Roscosmos cosmonaut Andrey Fedyaev, will lift off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida to perform science, technology demonstrations, and maintenance activities aboard the microgravity laboratory.
The flight is the sixth crew rotation mission with SpaceX to station, and the seventh flight of Dragon with people as part of NASA’s Commercial Crew Program. Bowen and Hoburg were assigned to the Crew-6 mission in December 2021 and began working and training for their flight on SpaceX’s human spacecraft and their stay aboard the space station. Fedyaev and Alneyadi were added as the third and fourth crew members in July 2022. Crew-6 will spend up to six months at the space station before returning to Earth.
The international crew will fly aboard the SpaceX Dragon Endeavour spacecraft, which previously flew NASA’s Crew-1, Inspiration4, and Axiom Mission-1 astronauts. As part of the refurbishment process, teams are installing new components, including the heat shield, nosecone, trunk and all forward bulkhead and service section Draco engines. These hardware components help the spacecraft withstand reentry heat, support docking and cargo space, and provide steering and thrust to the spacecraft. Previously flown components include pod panels from a previous human spaceflight mission.
As teams progress through Dragon milestones for Crew-6, they also are preparing a first-flight Falcon 9 booster for the mission. Once all rocket and spacecraft system checkouts are complete and all components are certified for flight, teams will mate Dragon to the Falcon 9 rocket in SpaceX’s hangar at the launch site. The integrated spacecraft and rocket will then be rolled to the pad and raised to vertical for an integrated static fire test and dry dress rehearsal with the crew prior to launch.

Mission Overview
Lifting off from Launch Pad 39A on a Falcon 9 rocket, Dragon Endeavour will accelerate its four passengers to approximately 17,500 mph, putting it on an intercept course with the space station.
Once in orbit, the crew and SpaceX mission control in Hawthorne, California, will monitor a series of automatic maneuvers that will guide Endeavour to the space-facing port of the station’s Harmony module. After several maneuvers to gradually raise its orbit, Endeavour will be in position to rendezvous and dock with its new home in orbit. The spacecraft is designed to dock autonomously, but the crew can take control and pilot manually, if necessary.
After docking, Crew-6 will be welcomed inside the station by the seven-member crew of Expedition 69. The astronauts of NASA's SpaceX Crew-5 mission will undock from the space station and splash down off the coast of Florida several days after Crew-6's arrival.
Crew-6 will conduct new and exciting scientific research to prepare for human exploration beyond low-Earth orbit and benefit life on Earth. Experiments will include studies of how particular materials burn in microgravity, tissue chip research on heart, brain, and cartilage functions, and an investigation that will collect microbial samples from the outside of the space station. These are just some of the more than 200 science experiments and technology demonstrations that will take place during their mission.
During their stay aboard the orbiting laboratory, Crew-6 will see the arrival of cargo spacecraft including the SpaceX Dragon and the Roscosmos Progress. Crew-6 also is expected to welcome the agency’s Boeing Crew Flight Test astronauts and the Axiom Mission-2 crew during their expedition.
At the conclusion of the mission, Dragon Endeavour will autonomously undock with the four crew members aboard, depart the space station and re-enter Earth’s atmosphere. After splashdown just off Florida’s coast, a SpaceX recovery vessel will pick up the crew, who will be helicoptered back to shore.
Commercial crew missions enable NASA to maximize use of the space station, where astronauts have lived and worked continuously for more than 22 years testing technologies, performing science, and developing the skills needed to operate future commercial destinations in low-Earth orbit and explore farther from Earth. Research conducted on the space station provides benefits for people on Earth and paves the way for future long-duration trips to the Moon and beyond through NASA’s Artemis missions.

To keep Frank safe. So we looked at taking some cargo straps from actually the CRS-26 vehicle. Those fit very well on the pallet. We were able to put the straps over Frank and then the seat liner if we needed to. And then secure him to the floor of the Dragon…. And we went and did all the kinds of analysis we do in terms of accelerations for the crew member. And those all came back acceptable… And then, you know, we could actually accommodate two more crew members in this cargo pallet area if we needed to.”
