What are the best seats in Delta Delta One Suite on JFK-AMS?
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-AMS?
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.

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.
