What are the best seats in American First Class on BUF-DTW?
Best: Row 1A and 1L are farthest from the galley and offer the most privacy. All seats have direct aisle access in the 1-1 layout. Avoid: Row 5 is closest to the business class cabin and may experience some noise from the galley area between cabins. Only 10 suites total on this narrowbody. The 1-1 configuration is unique for a single-aisle aircraft. Sliding doors on all suites. This fleet is being phased out as the A321XLR enters service.

Best: Rows 11-16 are designated Main Cabin Extra with 35 inches of pitch. Row 11 bulkhead has the most legroom. Exit row offers additional space. Avoid: Last row (22) has limited recline and is near the rear lavatory. Middle seats (B and E) are least desirable. Half of the economy cabin (36 seats) is Main Cabin Extra with additional pitch. Seatback IFE screens with live TV in all economy seats. Only 72 economy seats total, making this a very premium-heavy narrowbody configuration. Exit row seats on the A320/A321 family offer extra legroom but do not recline. The row immediately before the exit also has limited recline due to clearance requirements.
What are the best seats in Delta Delta First Class on BUF-DTW?
Best: Row 1 for maximum legroom as a bulkhead. Seats 1A and 1F offer window views with extra privacy. The 2-2 layout means no middle seats. Avoid: Row 3 is closest to the forward galley and lavatory.
