Last Friday (Feb 16, 2024), UA1639 was scheduled to perform a red-eye OGG to SFO. Exactly 20 minutes after take off, cruise attitude was reached at 34,000 feet. About 9 minutes after, the aircraft descended more than 23,000 feet in span of 6-7 minutes, and leveled at 10,000 feet. 20 minutes thereafter, the decision was made to divert to HNL, and finally about an hour after that, the aircraft (738 - N77510) landed safely at HNL. Hours later, the same aircraft took off bound for SFO.

I only discovered this by accident, and tried to piece it together based on flight tracking info (see some below). There is a personal account reporting the rapid descend was due to loss of cabin pressure, and oxygen masks were dropped as a result.

Anyone with any additional details?

I suspect that, thanks to the Alaska incident, any issue with pressurization on an aircraft with a door plug will meet with a similar reaction.

I see it returned to SFO on Monday as UA3863.
