Like all such things, devil in details.
Return flight of astronauts will be into the Atlantic Ocean for SpaceX Dragon, with accompanying costs left out for relevant ships and their crews for recovery.
Starliner returns crews in a Soyuz method, onto the ground at landing sites of White Sands, Edwards etc. Much cheaper.
SpaceX does their own splashdown recovery with their own fleet of ships. The government isn’t responsible except for the USCG enforcement of an exclusion zone.
