What are the best seats in Delta Delta One Suite on JFK-GRU?
Best: Odd-numbered window seats (1A, 3A, 5A, 7A and equivalent on right side) are positioned closer to the window and farther from the aisle, offering maximum privacy. Center pairs work well for couples when the privacy divider is lowered. Avoid: Seat 8A is an orphaned solo window seat in the last row of the cabin -- good for solo travelers but isolated. Even-numbered window seats are closer to the aisle with less privacy. All 29 passengers share only 2 lavatories, a significant downside vs the A350. 29 staggered suites with sliding privacy doors and do-not-disturb indicators. Memory foam cushions on all beds. 18.5-inch seatback screen is among the largest in the industry. Only 2 lavatories for the entire business class cabin is a notable weak point compared to 4 on the A350.
What are the best seats in Delta Delta Premium Select on JFK-GRU?
Best: Row 20 bulkhead has the most legroom. Window doublets (A-B and H-J) are ideal for couples. Row 23 passengers can stand behind their seat and still view IFE. Avoid: Center seats (D-E-F) in any row, especially in row 23 which is closest to the economy cabin partition. 28 seats in 4 rows. Premium amenity kit, enhanced meal service, and dedicated flight attendant. Adjustable headrest with privacy wings. USB-A and AC power at every seat.
What are the best seats in Delta Main Cabin on JFK-GRU?
Best: Delta Comfort+ rows 30-36 (56 seats) offer 34 inches of pitch with extra legroom, priority boarding, and dedicated overhead bins. Row 30 bulkhead has the most space. Window doublets (2-abreast) on each side are great for couples. Avoid: Last 2-3 rows near rear lavatories and galley. Center block middle seats (E and F in the 4-abreast center) are worst on long flights. 2-4-2 layout is more comfortable than 3-3-3 on competing aircraft for couples -- no middle-seat risk in the side sections. 56 of the 224 economy seats are Delta Comfort+ with extra pitch. Complimentary meal service on international flights. Delta Sync free Wi-Fi for SkyMiles members.
What are the best seats in American Flagship Business on JFK-GRU?
Best: Row 1 bulkhead seats (1A, 1L) offer the most space and privacy. Solo travelers should pick window seats (A or L). Center pairs (D-G) work well for couples traveling together. Avoid: Row 8 seats are closest to the premium economy cabin and galley. Center seats in row 8 (8D, 8G) may experience more traffic noise. Reverse herringbone layout with direct aisle access from every seat. No privacy doors on this older product. The Super Diamond seat is comfortable but lacks the enclosed-suite feel of newer products. Panasonic eX2 AVOD IFE system.

Best: Row 9 bulkhead offers the most legroom. Window pairs (A-B and H-J) are best for couples. Avoid: Center seats in the 3-abreast middle section are least private. Row 11 may have limited recline near the economy partition. Small premium economy cabin with only 21 seats across 3 rows. Located directly behind business class for quick exit. Separate meal service from economy.
What are the best seats in American Main Cabin on JFK-GRU?
Best: Main Cabin Extra seats (rows 20-22) offer 34-35 inches of pitch. Rows 20-35 are forward of engine noise profile and clear of rear galley. Avoid: Last 3 rows near rear lavatories are noisy and have limited recline. Middle seats in the 3-abreast sections are least desirable on long-haul flights. 9-abreast economy seating on the 787-9 is tight.
