Frequently asked
Which is better in economy: American or Southwest on BNA-MIA?
Main Cabin (American Airlines, A321neo) and Economy (open seating) (Southwest Airlines, 737-800) score virtually the same in economy: 3.7 vs 3.9/10. The biggest gap is legroom — 32" of pitch vs 30" — but neither carrier pulls ahead overall.
What are the best seats in American First Class on BNA-MIA?
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.
