Frequently asked
What are the best seats in Delta Delta One on SLC-LHR?
Best: Window seats 1A and 1L offer maximum privacy. Odd-numbered window seats (1A, 3A, 5A) are recessed closer to the window. Center pairs work for couples with divider down. Avoid: Even-numbered window seats are closer to the aisle with less privacy. Last row (row 9) is nearest to the premium economy curtain. 34 reverse herringbone seats with direct aisle access but NO sliding doors — this is Delta One, not Delta One Suite. Smaller 15.4-inch screens vs 18-inch on the A330-900. Same Thompson Vantage XL seat frame as the A339 but without the suite enclosure. 80-inch bed is generous.
What are the best seats in Delta Delta Premium Select on SLC-LHR?
Best: Window doublets (A-B and J-K) are ideal for couples. Row 10 bulkhead has extra legroom. Avoid: Center seat E in any row. Last row nearest economy curtain. 21 seats in 3 rows with 2-3-2 layout. Same Premium Select product as the A339 but fewer seats. Enhanced meal, premium amenity kit, dedicated flight attendant.
What are the best seats in Delta Main Cabin on SLC-LHR?
Best: Comfort+ rows offer 34-inch pitch with extra legroom and priority boarding. Window doublets avoid middle seats entirely. Avoid: Last 2-3 rows near rear lavatories. Center block middle seats (D and E) on long flights. 168 economy seats including 24 Comfort+ with 34-inch pitch. 2-4-2 layout is wider-body friendly — no 3-abreast middle-seat risk on the sides. 9-inch seatback screens (smaller than the A339 10-inch).
