Early morning after a second night of drinking wasn't nearly as bad as expected, but still not the most fun to be up well before sunrise and on the way to the airport. Maybe next trip I'll consider an afternoon departure instead so I can spend some time at Jewel Changi again.
Flight back was a tad longer than usual due to weather, blocked at 15 hours 45 minutes, and this time my upgrade didn't clear. Premium Plus (premium economy) on United is okay, they actually had an excellent pork lion by premium economy standards, but man, it still gets long. Food continues to improve at least; in particular the mid-flight chicken sandwich, which before was completely awful, is now actually quite edible (if still a carby disaster).
And the early morning arrivals are never that great either, although SFO sometimes does have beautiful sunrises if you're arriving in summer. Just make sure to avoid the Koi Palace Express locations at SFO as they're not anything like the actual Koi Palace restaurant; instead, think more Panda Express. *sad face*
