I don’t understand this. There had to have been 20+ degree difference in temp. Same aircraft, same airline, sat in roughly same area of the plane both ways. What drives one captain to freeze pax and another to toast them?
Most likely same aircraft-type but likely different aircraft, one with a working air conditioner, one not so much. There is a default temperature, but if the unit isn't working, that would explain it. If both flights were recent enough, you might be able to pull the data off of FR24... you should also report it so it can be looked at.
