What’s the real difference in cabin pressure and humidity between 787 and A350?

I’m planning a long-haul trip and I’m torn between booking a seat on a 787 or an A350. For those who’ve flown both on similar routes, was there a noticeable difference in cabin pressure and humidity that actually affected how you felt after landing?

I’ve flown both on the same routes. On the 787 the air felt less dry—my throat and eyes didn’t dry out as much—and I woke up with less congestion. It wasn’t dramatic, but it did help on those long nine‑hour hops.

Between the two, the difference to me was minor. Both planes had a similar cabin feel after long flights; I slept okay, but the real factor seemed to be the seat, the lighting, and how well I hydrated.

Could the real issue be hydration and how much water you drink during the flight rather than the plane itself?

Honestly, I’ve ended up thinking the route and the time of day matter more than the airframe. Some trips I felt the same on both, others I just found the schedule brutal no matter which plane.
