I've been a UA 1K for about six years, ever since I started putting most of my non-AC STAR flights into MP as Aeroplan began its own downward spiral. It's also meant flying a lot more UA both within NAmerica and overseas. Since it had no major routes into Canada, never flew CO until the merger though the majority of my flights have been on ex-UA planes/routes/crews. This week I had a chance to experience both airlines and found CO so far ahead of UA that it was actually like flying two different airlines! Flew a UA 777 from ORD-HKG-SIN-HKG in business and found the experience among the worst premium cabin experiences ever. I've never been a fan of the "new" C lay flats installed on the UA fleet. I find them cramped and lack any functional space for work or storage, not to mention any privacy. 2-4-2 is absurd when most airlines have gone or are going to 1-2-1. The front/back facing seats mean you're always staring at someone across the aisle, or they're staring at you! Nor is there a privacy screen between you and the person next to you in each seating pair. You can see what others are watching on their screens, and they can see what you're watching. The foot insets are too small to store anything in, and the shelf under the video monitor is too small to hold anything practical. Crews provided a blasé service going through their paces. The only segment I found bearable was between SIN-HKG since the seat next to me was empty and I finally had a bit of space and partial privacy. Then I flew HKG-EWR on a CO 777. What a difference! There was both space and privacy in a 2-2-2 configuration. The seat had functional storage and workable surface areas. And the crew was friendly, helpful and appeared to enjoy going through their paces. So while I endured the flight to Asia, I quite enjoyed the one back. I've actually shunned UA metal business class, preferring an E+ seat with an empty one next to me to wasting money and SWUs to upgrade. Unless I knew the flight was a CO one where the additional cost of W was actually going to get me a premium hard and soft product. Having moved much of my flying to AA in the past couple of years, I find even it's old international business product to be superior to the current UA product (on ex-UA metal). With DL having gone to 1-2-1 and AA undergoing this transformation, how can UA justify the product it provides on most of its wide body fleet? Can F be so lucrative that ex-UA planes have not been converted to ex-CO C seating standards?
