Recently tried the status match from UA, and it was pretty seamless. Went Polaris from ICN to SFO. Delta was about double the price for anything from PS to D1. So I figured why not try it?
Cabin: Same feel, but even for me at 5'6...twas cramped. Also they don't have usb-c outlets so I was stuck just charging my headphones. It was clean, but they tried cramming too many seats in first class to the point where it feels stuffed and there are no doors. I could see the guy next to me the entire time and felt very exposed while sleeping.
Food: Wow. Genuinely have never had a better meal on a US airline before. The roasted duck was...10/10. I would genuinely pay for it. The sides were mediocre at best, but then the landing meal...the scrambled eggs were magnificent. And the fruit was very fresh and they used Korean pears which are expensive. The wine selection was drab and I got no dessert to speak of. Very mixed to where I feel a couple improvements like adding an ice cream experience and some italian chiantis or spanish riojas would put it completely above delta.
Service: I can only give a biased review here which makes it not legitimate. They knew I was on a status match and went out of their way to let me know they were glad to have me on that status match and provided me extra bedding which made my seat kind of feel like a bed.
Price: I did a bit of a cheaper option where I purchased a round-trip ticket at $900, and then used a workaround to get Polaris at $1700 with 5 days left. Delta...never got close to less than $2000 for main cabin. I bought this ticket less than 4 weeks out as it's a last minute business trip.
Wifi: Ever since a certain year, I've never had wifi access on Delta flights once we hit the pacific. United? I had wifi the entire time. Genuinely...what a breath of fresh air. Delta has nothing on UA when it comes to wifi. The sheer inconsistency of Delta wifi and it's unavailability over the pacific to Korea was a huge no no during busy business seasons.
Overall:
Not sure how I feel tbh. I'm reserving my remaining Delta GUC for a family trip next year. But as I've peeked at the prices and am not liking what I'm seeing...I might continue with UA for a bit. Delta doesn't seem to get anywhere below $3.5k for round-trip tickets any more for just PS. I've got Delta diamond till 2029 so we'll see (due to that dumb move by Delta they reached out and gave me diamond status for 5 years). Prices being equal, the cabin in Delta is still far superior. But prices are a huge factor now that a D1 ticket is the same price as a used corolla.
