So, the plane's 25,000 ceiling was souped up to 37,000?


Service ceiling refers to the max height where an airplane can maintain
a specified rate of climb at max gross weight, but it's not a limit. If
you are patient, and especially if you are flying light, you may be able
to climb considerably higher.


Did they have, in effect, an air-lock? Or de-pressurize the whole plane?


Neither. I'm 95% sure that the Caravan is an unpressurized airplane, so
everyone would need to use oxygen at high altitudes. But there would be
no concern about pressurization or anything like an airlock.
