Frequently asked
Which is better in business: Delta or United on LAX-PVG?
Delta One Suite (Delta Air Lines, A350-900) beats Polaris Business (United Airlines, 787-9) in business, scoring 8.3/10 vs 7.2. The deciding factor: a closed suite door vs an open cabin.
Which is better in premium economy: Delta or United on LAX-PVG?
Delta Premium Select (Delta Air Lines, A350-900) and Premium Plus (United Airlines, 787-9) score virtually the same in premium economy: 5.5 vs 5.5/10. The biggest gap is seat type — recliner vs recliner — but neither carrier pulls ahead overall.
Which is better in economy: Delta or United on LAX-PVG?
Main Cabin (Delta Air Lines, A350-900) and Economy (United Airlines, 787-9) score virtually the same in economy: 5.1 vs 4.8/10. The biggest gap is seat width — 18"-wide seats vs 17.3" — but neither carrier pulls ahead overall.
What are the best seats in Delta Delta One Suite on LAX-PVG?
Best: Odd-numbered window seats (1A, 3A, 5A, 7A, 9A and right-side equivalents) are closer to the window and farther from the aisle for maximum privacy. Center pairs with the privacy divider lowered are excellent for couples. Row 1 has the most open space. Avoid: Even-numbered window seats are closer to the aisle with less separation from foot traffic. Rows 8-9 are nearest to the galley between business and premium select. 32 suites with sliding doors and do-not-disturb indicators. 18-inch seatback screens. 4 lavatories for business class, significantly better than the A330-900neo's 2 lavatories. The A350 is considered Delta's flagship long-haul aircraft. Dine-on-demand service on ultra-long-haul routes.
What are the best seats in Delta Delta Premium Select on LAX-PVG?
Best: Row 20 has the most legroom as the bulkhead row with extra separation from the galley. Window doublets (A-B and H-J) are ideal for couples. Row 20 is the clear top pick unless noise sensitivity is a concern. Avoid: Center seats in the 4-abreast middle section (D-E-F-G), especially E and F which have no aisle access. Row 25 may have limited recline near the economy partition. 48 seats across 6 rows in a 2-4-2 layout. Premium amenity kit, adjustable headrest with privacy wings, dedicated flight attendant, and enhanced meal service. The outside doublets avoid the middle-seat problem entirely.
What are the best seats in Delta Main Cabin on LAX-PVG?
Best: Delta Comfort+ rows (approximately 30-35, 36 seats) offer 34 inches of pitch with priority boarding and dedicated bins. Row 30 bulkhead has the most legroom. Avoid: Middle seats in any 3-abreast section on long-haul flights. Last 3 rows near rear galley and lavatories. Seat 55E is consistently rated poorly. 3-3-3 economy layout at 17.4-inch width is the A350's weakest point relative to competitors. 36 seats are Delta Comfort+ with 34-inch pitch. Remaining 190 Main Cabin seats have 31-32 inches of pitch. Complimentary meal service on all international flights. Seatback IFE and USB/AC power throughout. Delta Sync free Wi-Fi.
What are the best seats in United Polaris Business on LAX-PVG?
Best: Row 11 in the 4-row mini-cabin is the most private and quiet row in United's entire fleet, far from galleys and lavatories. Odd-numbered window seats (A or L) in rows 1, 3, 5, 7, 9 offer a privacy cocoon. Couples should pick center pairs (D-E) in odd rows. Avoid: Even-numbered rows offer less foot room, problematic for taller passengers. Seats near the mid-cabin galley (between main and mini cabins) experience more noise and traffic. Row 12 is closest to premium economy. Reverse herringbone 1-2-1 layout with direct aisle access from every seat. The mini-cabin (rows 9-12) is genuinely secluded and highly sought after. No privacy doors on this variant. Panasonic Ku-band WiFi; Starlink retrofit underway. 48-seat Polaris cabin is the standard long-haul 787-9 configuration.
What are the best seats in United Premium Plus on LAX-PVG?
Best: Row 20 bulkhead has the most legroom, though it lacks under-seat storage during takeoff and landing. Window pairs (A-B and H-J) are best for couples on overnight flights. Avoid: Row 20 lacks under-seat storage. Center seats in the 3-abreast middle section (D-E-F) are least private for sleeping. Row 22 is closest to economy. Small 21-seat cabin in 3 rows. 2-3-2 layout is standard for Dreamliner premium economy. Complimentary meal service with premium wine selection. Separate meal and beverage service from economy. Adjustable headrests with wings for sleeping support.
What are the best seats in United Economy on LAX-PVG?
Best: Rows 35-38 are the forward economy rows, closest to the mid-cabin lavatory and away from the noisier rear. Window seats benefit from the 787 Dreamliner's larger electronically dimmable windows. Avoid: Row 57 (last row) has limited or no recline and sits right against the rear galley and lavatories. Rows 55-57 experience significant galley noise and crew traffic. Row 35 near the mid-cabin lavatory can be noisy. 9-abreast seating at 31-inch pitch is tight for long-haul flights. Complimentary meals on international routes. USB-A ports and AC outlets at every seat. The 787 Dreamliner cabin features higher humidity, lower cabin altitude, and larger windows than conventional aircraft, reducing jet lag.
